I didn't even hear about this. Its a scary scary world though! I don't have many dealing son craigslist, but I've been contacted by some strange people. I always go with my gut feeling though. If someone creeps me out through email, there's NO WAY I'm going to meet them in person!
I usually bring a strong guy with me, or my dog. Not too many people will mess with you when you have those two things around! I still don't like the idea of meeting people, but when I do, I make sure its a populated area. I've never had issues before, but you never know what can happen!
