ELI5 : Illegal Activities on Television

May be a dumb question but I've always wondered...How do the people on television who show their faces and names while uncovering their illegal business/activities not get caught and thrown in jail? 
Ex. Moonshiners, new series Tickle, multiple series on drugs etc...

Ok, so you're a cop.  You see Snoop DogLionWhatever smoking a huge joint on tv, right there in your town.  So you decide you're going to arrest that guy.

He shows up in your town again, and you arrest him.  Then his lawyer appears and asks how you know he was smoking an illegal substance on that video.  Do you have any actual evidence as to *what specifically* he was smoking?  No?  Then prepare for a media circus and a lot of expense resulting in a probable acquittal, all over a very minor charge.
