Mohammed Goes On Machete Attack at Nazareth Restaurant

Any guesses why?  From 2/12/16 NBC News:

An Ohio man who slashed four restaurant patrons with a machete and was later killed by police had come to the attention of the FBI four years ago for radical comments, law enforcement officials said.
Agents took a brief look at Mohamed Barry but moved on, the officials said. The officials did not elaborate on the radical comments.

Investigators said Friday it is unknown why Barry, 30, attacked patrons at Nazareth Restaurant and Deli in Columbus shortly after 6 p.m. Thursday, or why he struck at that restaurant.

Barry was shot and killed by police at the end of a five-mile chase shortly after the rampage....

Investigators are looking into whether Barry attacked the restaurant in the mistaken belief that owner Hany Baransi was Jewish, sources told NBC News. He is actually an Arab Christian from Haifa, Israel. 

And Trump is crazy for saying to stop bringing in Muslim refugees?
