What rights does a private citizen have to aid in law enforcement? Suppose you witnessed a robbery or theft from a store in the United States and saw someone running with the stolen goods, and you yell, "Stop, thief." Are you within your rights? Suppose you see someone running, and the police chasing him. If you were brave or foolhardy enough to do this, are you allowed to try to trip or grab or push this person to slow him down so that the police can catch up, or would this be assault? Do the above actions fall under citizens' arrest?
So for your first question, yelling "Stop Thief" loudly at the thief is perfectly legal (Like Yelling "Fire" in a crowded theater, it's legal if the theater is infact, on fire... the quote implied that it was a prankster who drew amusement from the reaction of the people who took him seriously). This may alert store employees, who have a specific kind of Citizens Arrest Power known as "Shopkeeper's Privilege" and is a reduced liability compared to Citizens Arrest. This is also pretty basic self defense agains people who are not engaged in any physical action against you but are starting to scare you. Suddenly shouting draws attention to you and discourages them from their behavior "I SAID DON'T TOUCH ME" being suddenly shouted in a Wal Mart is going to get notices from the immediate crowd drawn to you, and by poximate location, the person who is making you uneasy. For your second question, maybe, it depends... since the cop is clearly chasing the guy, you meet the qualification to use non-deadly force in stopping the criminal (i.e. you are witnessing a person committing a crime, in this case, resisting arrest or persuit) and it would certainly be reasonably non-deadly force if you were to trip, grab, or push the fleeing suspect. Citizens Arrest doesn't specify a minimum time to qualify, so if the officer is seconds behind, and you detain the criminal in this action until the gap is closed, it still counts.
england-and-wales Initially, one should comply with the officer's instructions as he has the power under statutory Stop &amp; Search powers to detain someone for the purpose of the search (discussed here). Failure to do so may be an offence. If, subsequently, one considers the search and detention was unlawful, the first port of call is to lodge a complaint with the relevant police force who - depending on the circumstances - may escalate the complaint to the Independent Office for Police Conduct IOPC. You can complain directly to the police/other organisation (see ‘Who can I complain about?’ below for a list of the other organisations) or via the IOPC. If you complain via the IOPC, your complaint will be sent direct to the organisation involved. They will assess your complaint and contact you about how it will be handled. The IOPC will not be involved with this initial assessment of your complaint. If the complaint is found to be valid, then any offence committed by not complying with the office would (in all probability) be overturned on appeal. As well as any compensation awarded by the court, the Chief Constable may consider making an ex gratia payment (mentioned here). Note that there is no obligation to do anything if the interaction falls within the Stop &amp; Account provisions.
Foreign citizens are just as entitled to Fourth Amendment protections against search and seizure as American citizens are. The case you cited was, in fact, a South Korean citizen who successfully had evidence suppressed from an unjustified border search.
Any society that makes rules will make rules that generally favor the people in power. Police are an essential component of a system that is built to maintain power for the people who are powerful, and there are few incentives for politicians, prosecutors or judges to punish them for maintaining order, even when they do so in ways that most people would think are not civil. Anyone involved in creating the law therefore builds systems to protect themselves -- and each other -- from accountability. The police fail to meaningfully investigate themselves, the legislature erects barriers to accountability (Sec. 614.022, for instance), and the courts routinely provide them immunity for their wrongdoing. So yes, there is a difference in how our legal system treats law enforcement and how it treats everyone else. I don't know anyone with any experience in the law who would even try to pretend otherwise.
You don't know. You can't know. And you can't force the officer to tell you. Detention Status As a practical matter, you have no way of knowing if you are compelled to follow an officer's order because you are being detained unless the officer volunteers that information (your detention status) which they are not compelled to disclose and have every incentive not to disclose. Consider the situation when the officer does not have reasonable suspicion do detain you. If the officer instantly informs you that you are "free to go" then you are likely to leave and end the encounter immediately. However, if the officer says nothing, then you might stay and inadvertently say or do something that would give the officer reasonable suspicion to detain you from that point forward. Your behavior during that detention could lead to probable cause, arrest, etc. Every officer knows they have nothing to gain by being quick to tell you you are free to go. Deceptive Conduct To compound the issue, police encounters are particularly problematic because police officers have a lawful right to engage in deceptive conduct during an investigation including but not limited to lying. You, on the other hand, can be prosecuted for lying to the police conducting an investigation. (See this article for more information.) Hobson's Choice Therefore, all things considered, police encounters present a Hobson's Choice. Either comply with every order in an effort to end the encounter quickly. Or try to press the officer to determine whether you are "being detained" or "free to go." The former course of action voluntarily cedes some of your rights. The latter risks "provoking" the officer into making your encounter more difficult, painful or costly than it otherwise might be. Never Consent to Searches That said, you are never under any obligation to consent to a warrantless search of your home or vehicle. Typically, saying, "I do not consent to searches." is usually sufficient if asked. Evidence obtained from warrantless searches is barred from being used at trial unless you waive this right by consenting to the search. See this question (and answers) if you are concerned about the officer falsely claiming you gave consent if you didn't. Never Talk to the Police As a legal matter, talking to the police can never help your case in court. Anything you say to the police that might help your case (i.e., exculpatory) is not admissible as evidence because it's hearsay. On the other hand, anything you say to the police can and will be used against you. In fact, even if you are completely innocent of all crimes AND you are completely 100% truthful to the police, you can still give the police all they legally need to convict you of a crime simply by talking to them. Whereas, without your statement, they would not have had sufficient evidence to convict. See this Youtube video for more details and examples of how this can and does happen every day. Practical Matters The above analysis presents the reader with some practical concerns. You don’t want to risk being harmed by an officer in fear for his safety. You don’t want to be handcuffed and taken to the police station if you can avoid it. You must obey all unconditional commands of a peace officer. It does no harm to inform the officer that you are willing to comply with all unconditional legal commands and ask him or her if a given command is, in fact, unconditional. Some attorneys go in the opposite direction from the "never talk to the police" rule and advise that, say in the case of a domestic violence dispute, the best course of action is to answer police questions matter-of-factly, never lie and never admit guilt. That course of behavior can avoid a potential trip to the police station in handcuffs in the back of a police car even if you are never ultimately arrested. TL;DR: Police encounters are tricky. It's difficult to know what to do. The best course of action is to educate yourself about your rights and the law and apply judgment and common sense to guide your behavior to achieve the best outcome. I am not an attorney.

Police officers can lie to you He asked to search your car. He’s allowed to do this. You said no. You’re allowed to do this. He lied to you when he said he would get the K9 to search the car - this would not be legal. But he’s allowed to tell you lies. You made an admission of criminal activity. He now has probable cause to search. He legally searched, confirmed your admission and booked you. Seems legit to me.
There is a state law that requires you to obey the police: ORC 2917.13, which says you may not Fail to obey the lawful order of any law enforcement officer engaged in the law enforcement officer's duties at the scene of or in connection with a fire, accident, disaster, riot, or emergency of any kind. If you do, misconduct at an emergency is a misdemeanor of the fourth degree. If a violation of this section creates a risk of physical harm to persons or property, misconduct at an emergency is a misdemeanor of the first degree. You also cannot Hamper the lawful operations of any law enforcement officer, firefighter, rescuer, medical person, emergency medical services person, or other authorized person, engaged in the person's duties at the scene of a fire, accident, disaster, riot, or emergency of any kind "Hamper" is not defined statutorily, but the plain meaning of "hamper" is not the same as "fail to assist". We have not established that the order is lawful, however, which is crucial. The police cannot just freely search a residence without permission. If they have permission from the occupant, they can search and seize. If they have probable cause to believe that a crime exists and the circumstances make a warrant impractical, they can search and seize. I don't know what you mean by "wellness check", but that seems plainly to be unlawful entry. However, if the resident calls 911 and reports that he is having an issue, that is sufficient consent for entry. In the case of a fire alarm, the fire code authorizes a fire department official in charge of an actual emergency response incident to order the evacuation of a building, and occupants are required to comply. If we suppose that the smoke detector in a room has gone off, the fire department is authorized to inspect for fire, and there is a provision under the law about failure to obey a lawful command (to open the door so that they can look for fire). Problem: you cannot know whether the order is lawful. The officer doesn't decide what is lawful, the courts do (after the fact), and typically a command is found to be lawful unless it is clearly unlawful. The order from your supervisor is not "enforceable" in the sense that you cannot be arrested, imprisoned, or fined for disobeying your boss. However, there is a potential club they can use against you, namely firing you for disobeying the order. Normally, you can be fired for wearing the wrong shirt. But there are laws about employers doing illegal things, such as ORC 4113.52, which provides recourse when the employee reasonably believes that the violation is a criminal offense that is likely to cause an imminent risk of physical harm to persons or a hazard to public health or safety etc. In which case you report this to the supervisor, they have 24 hours after getting the report to correct the situation, and after that you would report the situation to the county prosecutor. (Read all of the details in the linked law, don't just skip steps: this is an executive summary). Having done this, you are protected from being fired, demoted. reassigned etc. The employer will be strongly motivated to not incur the penalties for violating the whistle blower statute. Additionally, you can sue the employer if they fire you for refusing to violate the law (termination in violation of public policy).
What do you mean by "a public building"? Just because a place is owned by the public, doesn't mean anyone can go there any time they wish. Military bases, firehouses, and jails are owned by the public, but many of these have limited access to the public. It may be open to the general public, but that does not mean restrictions cannot be put into place, either on times, or activities, or individuals. For example, public parks often have time and activity restrictions; schools have the power to restrict individuals from their premises, either specifically or by general category. As a general point of law, the owner of any property, or their agent, can order anyone without the right to stay (e.g. not a co-owner or tenant), and that person must depart, otherwise that person is tresspassing. Assuming that the Senior Center is owned by the town, it is probable that the Administrator is empowered to act as the town's agent in this matter. Now, since this "No Trespass order" is specifically directed at you, there is a reason behind it. It may be something you've done. It may be that complaints have been received about your behavior. It may be an actual abuse by someone who doesn't like you. We have no way of knowing. It the order itself doesn't give you a hint as to why, you can ask the town administrator for the reason. As for being against your rights, there is nothing inherently illegal about this situation(that is, an agent of a property owner exercising the latter's right to prohibit an individual from said property), but some of the details, especially why it was specifically applied to you as an individual might be a civil rights violation.
