Can Clinton be pardoned without being charged or convicted? Is it possible for someone to be pardoned if they haven't been convicted or even charged with a crime?
The canonical example is Gerald Ford's pardon of Richard Nixon.
Possibly. I wonder if you mean "convicted" rather than "arrested"? There is no way that he will be "arrested" because you don't accompany him ("arrested" is when he taken by the police before a trial). On the other hand, if he plans to call you as a witness for the defence, then your absence may mean he is convicted at his trial when otherwise he would be found innocent. The final possibility is that you might act as a character witness after conviction, and your absence may mean he is sent to jail rather than fined. It may be possible for you to write a witness statement describing what happened, and to have this notarized. On the other hand, the prosecution may well want to cross examine you. I am pretty sure you can write a character witness statement (saying, if true, that it's a first offence and that you have forgiven him, etc) and get it notarized. That might persuade a court to be lenient. I think you (as a couple) need to talk to his lawyer.
If that which you describe in your comment ( Facebook post as only basis for warrantless search) is, and can be shown, to be the only basis for the search, and there was no evidence of a crime in plain view when they arrived.....then yes, it is likely the search and all evidence acquired from the search would be excludable. As to whether the individual could still be prosecuted, that depends if a case could be built independent of the evidence collected during the search.
Generally, no. The party to the action will be the State (commonwealth). The prosecutor acts as the agent of the state. The sheriff is not a party and cannot appeal.
If you read the first link, every offense can lead to arrest without a warrant. Notwithstanding, you don’t have to be arrested to be charged and vice -versa.
Yes, because the crimes are different instances. Let's remove the guilty plea and the fact that it is murder: can a person assault a person, be tried and imprisoned, then assault the same person later – and get off by declaring "Double jeopardy!". No, it's not the same crime. It's the same type of crime, and involves the same victim, but it is still a different crime. The same with your proposed scenario. (Incidentally, your first line is wrong: the woman wasn't murdered, she was thought to have been murdered).
However, in the last 233 years, only a handful of people have been prosecuted for violating this law. The census bureau has noticed that a more effective way to get everyone counted is to follow up in person if someone neglects to respond to the questionnaire. Once they follow up and the person has responded, there's no longer a basis for prosecuting. What is the point of one of the oldest laws, in which some people have cared enough to amend, but not enough to actually enforce? The possibility of prosecution is presumably thought to increase the response rate even if virtually nobody is ever prosecuted. The law also serves as a formal statement by congress that responding to the census is important, even if the executive doesn't prosecute people for failing to do so. Another thing to consider is that an element of the offense specified in 13 USC 221 is refusal or willful neglect. Without evidence of an affirmative refusal to respond, the prosecutor would need evidence of willfulness, which goes to state of mind, and that is notoriously difficult to prove. Any defendant who claims to have intended to respond but for chronic forgetfulness would introduce reasonable doubt unless the prosecutor had something to show that the defendant intentionally refrained from responding.
No The police and the office of the public prosecutor have discretion in which cases they investigate or prosecute. The court may refer an instance of criminality to them but they are under no obligation to do anything with that referral.
