When I first got started in forensics it was when chat rooms and webcams were taking off – so pedophiles thought they'd be able to figure out who was who on the internet since clearly you'll know you're webcamming with a 40-year-old dude munching on donuts instead of a 14-year-old girl. I was a naive 18-year-old woman who was just getting started in policing, doing some clerical work for my hometown police department when I heard a couple people talking about how they were having a hard time chatting up creeps now that webcams were a thing. I told them why not just hire someone to act like an underage girl or boy and coach them on what to say and how to set up meetings to catch these assholes.
Lo and behold I volunteered myself for the job. We set up a 'bedroom' in one of the upstairs offices complete with a bed, a desk, and some posters from one of the officers teenage daughters. I had to wear some of my high school sports clothes or pajamas while talking to predators via Webcam – I passed notes back and forth with the team of officers and passed it off as trying to do homework while chatting. The hardest part was to still seem interested and innocent while this dude on the screen is telling me what type of horrible things he wants to do to my body thinking I'm still a child.
