Shocking video emerges from NYC cathedral shooting

Video has emerged that shows the moment an armed gunman was fatally shot by the NYPD on Sunday after he opened fire during a Christmas concert outside a church in New York City. 

The video, which is about four minutes long, was posted on Facebook by a person who attended the outdoor concert with his family at the Cathedral Church of St. John the Divine in Harlem.

In the video, the gunman, who was dressed in black, can be heard shouting, "kill me, kill me," before he is fatally shot on the steps of the cathedral. 

"I figured that I should take a video of this thing that could have been far worse than just the shooter getting shot and killed," Steven Wilson, who posted the video, wrote. He said he only recorded the video after he knew his family was safe.
