This is an incredibly weak argument, because the actual hard data is here for everyone to see, and you are completely disregarding it in favour of an unconfirmed anecdote. The CS community is pretty big, and according to the stats page (http://www.couchsurfing.org/statistics.html http://www.couchsurfing.org/statistics.html), there have been over 1.3 million positive traveling experiences. Your argument seems to be projecting one negative anecdote against that entire dataset. Criminality rates in pretty much any city are far beyond 1/1.3M, so do you also feel we should restrain from all social contact? If anything, i actually see CS in general as a perfect example that generalized fears of insecurity are typically misplaced, and that while it's useful to take precautions, you are only really punishing yourself by not being more open to all the different cultures and perspectives available for free at your doorstep.
