◙October 23, 2014: Zale Thompson injured two
New York City police officers, once critically at a
Queens, New York shopping district by striking them with a
hatchet. 4 officers were posing for a photograph when Thompson charged them. The police opened fire killing Thompson and injuring a bystander. Thompson who converted to Islam 2 years before the attack posted "anti-government, anti-Western, anti-white" messages online. His attack was classified as an act of
terrorism.
These are the acts of terrorism related to Islam, there are many more, but they have been attributed to other factions than Islam. Islam isn't the only source of crazy idealism out there.
