Actually, you just proved my point -for- me, thanks. Those links you provided show a single successful school shooting; in
1974 It was shortly after the shooting you mention that Israel armed its' teachers, and they havn't had a successful attack since. The second link/article references a shooting which took place
off school grounds and in an area where their teacher was prevented from carrying a weapon.
As for this second article:
1: Try comparing the rate of violent crime in Dallas to that of Washington DC; victim-disarmament capital of the country and one of the Top 5 most dangerous cities for over 30 years now. ( Murder rate; 60+ per 100,000 )

2: I'll admit that Dallas seems to be somewhat of an anomaly in the concealed-carry phenomenon. However, its' rate of violent crime is dropping along with the rest of the country, and it also has to deal with factors that many more northerly cities don't, such as the increase in crime which is associated with certain segments of the illegal immigrant population. How do you, however, explain the greater-than-average drops in violent crime in those areas which have enacted CCW? How do you explain the precipitous rise in violent crime in the UK and Australia since their near-total gun ban?
