Is it? By their own admission they have ample evidence, needed to prove their time
It seems to me that there is really a lot of media out there bragging about committing past crimes, and profiting from it. I don't think it's a good thing, but for whatever reason clearly people are able to do that without repercussions.
This reminds me of the California law banning the use of rap lyrics as evidence in crimes. Much of popular rap music is directly bragging about committing specific crimes and getting away with it, yet those people remain free, and make a lot of money off of it.
