Well, this is something that you don't see everyday....An assailant's jacket stopped NYPD bullets! What's odd is that his jacket was just a regular off the shelf Carhart! 
The guns? Presumably Glock 19's loaded with 124gr Gold Dot.

"A sergeant and an officer fired a total of nine rounds at 46-year-old Garry Conrad on Wednesday, with one of the shots killing the depressed Broadway stagehand who refused to drop the blade at West 49th Street and Eighth Avenue. Four of the bullets got lodged in Conrad’s Carhartt jacket, sources said, adding that he was not wearing a bulletproof vest."

I am a little curious what they find out, as Gold Dots are kind of a gold standard for defensive bullets! 

And in other news, today at the White House the Secret Service did not have such a failure. Source: http://www.cnn.com/2016/05/20/politics/u-s-park-police-shooting-near-white-house/

"A Secret Service spokesman said the incident occurred shortly after 3 p.m. ET when a man carrying a gun approached a checkpoint on E Street near the White House. The suspect was given verbal commands to stop and drop the gun, and when he failed to comply, he was shot once by a Secret Service agent and taken into custody. Secret Service officers and an agent provided medical aid to the suspect, and the city's EMS said he was transported to a local hospital with critical injuries.

I believe that the Secret Service still carry 357SIG loaded with 125gr Gold Dot. No word on that assailant's jacket however.
And the internet caliber debates rage on....
