Orange County, California (CNN) - "Hello? Hey, what are you doing, girl? You just woke up? You going to be free to hang out in a little bit?" Shane, a vice unit undercover investigator, is on the phone with a woman who placed an online ad offering adult services.
"Okay I'm going to head down to the Disneyland area and get a hotel." He's making a date, and choosing his words carefully.
"I just want to make sure I get what I need. Are you bringing condoms or do I need to bring condoms? You've got some? And it's 200 for an hour right?" Shane has become an expert at scoring that important criminal admission over the phone - making sure there is no confusion that sex is expected on this date.
"From what I found, sometimes you can use too much jargon," Shane explained. "If you use too many street terms you can come off like a cop so I almost talk to them like, "Hey this is what I'm looking for" - just common terms and maybe throw in just a little bit of street jargon.
"If you call them rude or real vulgar they'll just hang up on you. So, to them it's a business and they run it like it's a business, so there's that fine dance you have to do with them in negotiation you have to play to get the deal to work."
Officers in California scour online dating ads looking for possible human trafficking victims - and then arrange a date.
They say one of the hardest parts of the job is dealing with traumatized women who don’t think they can successfully escape.
The operations - part of the Orange County Human Trafficking Task Force - include setting up an undercover sting and trying to catch the woman’s pimp.
