Well the latter is question is because no defense attorney no matter how incompetent and overworked is going to let their client be interviewed like this, so anyone who lawyers up is not going to appear in this kind of interrogation footage, as they aren’t being interrogated.
The same goes for the former question too, as in you don’t see all the people who decided to claim the 5th, as there is no interrogation footage and it doesn’t make very good TV (and they are presumably much less likely to end up being charged, I don’t know if the show favors cases where a suspect is charged at the end?)
