To be fair, serious violence in most American schools is rare, too. There's a study linked from the article commissioned by the US Department of Justice: http://www.ojp.usdoj.gov/bjs/abstract/iscs08.htm http://www.ojp.usdoj.gov/bjs/abstract/iscs08.htm One telling statistic that it provides is that during the '05-'06 school year, there was an average of one "serious violent crime" experienced per 1000 public school students (defined as "rape or attempted rape, sexual battery other than rape, physical attack or fight with a weapon, threat of physical attack with a weapon, and robbery with or without a weapon." -- and you can bet that "threat of physical attack" and "physical attack or fight" is fairly loosely defined.) 1 in 1000 per year is satisfactory, if you ask me. I don't think you can do much better than that among the population as a whole without sacrificing a ton more privacy and freedom.
