The axe-wielding radical black Muslim who hacked two cops in Queens recently had spent months viewing jihadist material online and stalked police for hours before launching his attack

Detectives piecing together the life of Zale Thompson, 32, say that in the nine months before his attack on October 23, 2014 he had visited 277 websites relating to ISIS, beheadings, Al Qaeda, and jihad. Thompson was shot dead after running up to four officers in New York brandishing a hatchet, before wounding cop Kenneth Healey, 25, in the head, and slashing another in the arm.
