Cool! I get to post the 50000th post on this board.
Anyway, Jimmy, I went to WSG and followit to its source at
http://insidecostarica.com/dailynews/2005/may/16/nac02.htm. It indeed said 25%, but I still have to believe that was a typo. If crime was anywhere near that extensive in CR you would be reading about it in the US papers and no one would be going to CR.
That WSG thread had exactly 3 articles with any real information on the subject of crime in CR. One was the typical US embassy warnings. Go to their website and you will find similar or often even more alarming advisories on other countries. They offered a lot of good advice but when they tell you things like it is dangerous to sit in the front seat of a cab or you're legally required to wear a seatbelt in those cabs you have to realize that they are being overly cautious. There were also a couple of articles from some CR newspaper sites that bemoaned rising crime. You get stories like that everywhere, since its a problem common to a lot of places. I don't want to minimize the problem and it is certainly getting worse, but I wouldn't read to much into those either.
Most of the crime happens to people who are careless, off their guard or fail to follow some basic precautions. BTW, I also saw in that thread that you went with a street girl a few times on this past trip. That's one really good way you can increase your risk of being a victim of crime.
