Islamic Terrorism - Keeping Score

Following the shootout in Garland TX, there are lots of brave hoots and hollers celebrating a score of
Islamic terrorists         Regular Americans
0                                   2

I took a cursory look and in the last 40 years or so, there have been some 75 attacks by people claiming an affinity with Allah as an excuse. Some were describable as jihadi attacks and some were in the cultural no mans land of honor killings which are still about a Muslim killing someone for not being sufficiently Muslim. Even the total number of attacks is suspect on account of the beltway snipers deeds all being listed separately as were the 4 airplanes used on 9/11.

The article does not list the fates of the attackers although 18 died on 9/11, and one each from the Beltway and the Boston marathon actions. If we add in the two from Garland, the score for the last 40 years is about:
Islamic terrorists         Regular Americans
3,103                          22

If this isn't a call for less back-slapping and high fives and more vigilance, I don't know what is.
