I was just thinking...

I was reading about this Philip Markoff, the alleged Craigslist Killer....
And I was thinking that if I was a hooker, I would take a picture of my client to SMS to my pimp every time, at the onset of every encounter. It might kill business a little bit, but if anyone ever killed me, it would be a good way to catch them right off.
I don't know, I think a guy would think twice before killing a hooker who already sent out his picture...
