Not-so-shockingly, a Muslim convert.

A New York man pleaded guilty Wednesday to plotting an attack on American police and soldiers returning from Afghanistan and Iraq. Jose Pimentel (a/k/a Muhammad Yousuf), a Dominican convert to Islam living in Harlem, wanted to use homemade pipe bombs in the attack.
According to the original criminal complaint, Pimentel’s website, .trueislam1.com, advocated violence against Americans. For example, an article titled, “Why Usamah Ibn [sic] Laden is the Leader of the Believers,” said that “People have to understand that America and its allies are all legitimate targets of warfare. This includes, facilities such as army bases, police stations, political facilities, embassies, CIA and FBI buildings, private and public airports, and all kinds of buildings where money is being made to help fund the war.”
In recorded conversations with a government informant, Pimentel discussed targeting Americans using explosive devices, including killing returning marines and soldiers who fought in Iraq and Afghanistan. He suggested buying bomb components from Home Depot. “That is what I really want to get into because it’s so cheap and it could do a lot of damage,” Pimentel said in a September 2011 conversation. “[A]nd then that’s something worth going to jail for, you know. Like, if you get caught because you blew up half of a side of a police station.”
