They ended in conviction, but a lot of the cases are slowly being overturned/ still in trial (partially due to a bloated criminal justice system). Two of them were overturned in 2009 on the grounds that there was no real victim in the alleged crime because they decoy and everyone involved in the chats/calls were of consenting age.psrdirector said:looked it up, most fo the cases end in conviction, the only time it didnt in mass was the murpy where the guy killed himself, his office (after he died) decided not to prosecute claiming no evidence, the orginization that did To Catch a Predator, claimed they did it out of cowardice because of the suicide (not really they just said the coward part, im guessing the suicide was implied)
so the show isnt even on any more btw
Also it is probably a very state to state problem or a bunch of the guys can't afford anything more than a useless public defender to do the legwork to overturn it.
Also the cases/stings started as early as 2004, with a 5ish or so possible prison sentence + getting off for good behavior/parole etc I'm sure a lot of these guys probably are just waiting out their last few months before they get out and bothering with the long amounts of time/money now that a legal precedent to overturn the ruling is set it just is pointless.
