Somebody Hasn't Read Their Quran Very Well

From a recent story in the Delcotimes:

New Philadelphia Mayor James Kenney has cautioned the public against associating the police officer’s shooting with any teachings of Islam. Members of the Upper Darby Islamic Center that is 1.1 miles from the shooting scene said last week that they are not familiar with the suspect and noted that the Quran, the central text of Islam, does not justify shooting or killing.

Question:Does the Quran really contain dozens of verses promoting violence?

Summary Answer:The Quran contains at least 109 verses that call Muslims to war with nonbelievers for the sake of Islamic rule.  Some are quite graphic, with commands to chop off heads and fingers and kill infidels wherever they may be hiding.  Muslims who do not join the fight are called 'hypocrites' and warned that Allah will send them to Hell if they do not join the slaughter. Unlike nearly all of the Old Testament verses of violence, the verses of violence in the Quran are mostly open-ended, meaning that they are not restrained by the historical context of the surrounding text (although many Muslims choose to think of them that way).  They are part of the eternal, unchanging word of Allah, and just as relevant or subject to interpretation as anything else in the Quran. The context of violent passages is more ambiguous than might be expected of a perfect book from a loving God.  Most contemporary Muslims exercise a personal choice to interpret their holy book's call to arms according to their own moral preconceptions about justifiable violence.  Their apologists cater to these preferences with tenuous arguments that gloss over historical fact and generally do not stand up to scrutiny.  Still, it is important to note that the problem is not bad people, but bad ideology. Unfortunately, there are very few verses of tolerance and peace to abrogate or even balance out the many that call for nonbelievers to be fought and subdued until they either accept humiliation, convert to Islam, or are killed.  Muhammad's own martial legacy, along with the remarkable stress on violence found in the Quran, have produced a trail of blood and tears across world history.

Even the Bible justifies killing, if not shooting. (They didn't have guns back when it was written.) If tens of thousands of Muslims weren't practicing this sort of violence against fellow Muslims and Westerners it wouldn't be a big issue. But...
