I've been working PC repair 30 years, never run into any CP. Of course I wasn't going through people's files looking for shit to steal like the Geek Squad guys, and I would always say if they wanted files backed up "If you have me do this I may see any of those files, so do not have anything in there you do not want me to see and have me back it up" and I've never come across a single case of CP
Oh don't get me wrong there were plenty of cases where a nice bottle of brain bleach would have been nice, such as the gal whose desktop was a constantly revolving pile of her fat hairy BF's taint and nutsack pics, the gal that had made a ton of pics of herself posing with her dildos that I swear were so big they could go in a gunrack, or the guy who had a porn bug that wallpapered the screen with vids in the "2 girls 1 cup" vein, but no CP.
Now that said...I'm sure I'm gonna get hate for this but I have to agree with my friend that works at the state crime lab on this very subject that most of the guys you see caught with CP? Really need to be getting mental help versus jail time. he said anybody whose done any field work in this area can spot the difference between the actual predators and the porn addicts in like 10 seconds, the predators are setting themselves up with jobs where they can get to kids, volunteering at places where they can get at kids, they are like sharks heading to the area where there is the most prey. He said those guys? Life without parole, there is nothing you can do to stop them attacking kids except throw 'em in a box or a bullet to the head.
Now compare that to the porn addicts or as he calls 'em "socially retarded"...they have zero contact with kids, most have little contact with anybody if they can help it, you look at their record and they often haven't even gotten a speeding ticket, its like night and day compared to the predators. They also have these HUGE collections of porn and they always follow the same pattern, the oldest is straight porn, then mild kinks like anal,trans,gangbangs, then BDSM until they reach bestiality and CP. He said they just sit and watch so much porn they become unable to even get aroused on anything short of the most perverted shit. A perfect example was one they had awhile back, when his mom died in 1998 he simply stopped leaving the house, paid everything online or by phone, and to get him out of the house in 06 they had to tranc him. That guy is doing 65 years on the taxpayer's dime when a couple years in a mental health facility probably would have fixed the issue.
