[ELI5] How can television shows film illegal activity and the broadcast it without prosecution? 

How can shows such as "Moonshiners" on the Discovery Channel be made. Why aren't the people in the show that are making moon shine, tracked down and arrested? Why do these people doing illegal things allow themselves to be videotaped and put on national television?

You have to be able to prove that the crime was actually being committed, which is easy for some crimes because footage of it being committed is undeniable (murder, rape, running a stop light). Other crimes, like doing illegal drugs have to be caught in the act. If you have a video of someone snorting cocaine, they can claim it was powdered sugar or something and there's no real way you can prove they're lying. Even if the police have video, they have to also prove that they caught THAT exact person doing THOSE exact drugs at the time it happened.
