Here is the aftermath of the attack via the NY Daily News, which reported on it.
"Here is the statement issued by NYPD after the attack.
"Coming from another generation, he hadn’t learned the difference between the Woman’s March (peaceful) and ANTIFA, and one might also lay blame for his attack on the media, which refuses to accurately report on the hundreds of violent attacks committed by masked men.On Saturday, January 20, 2018 at approximate 2230 hours, police received a pick up job of a 30 year-old male punching and choking a 56 year-old male at the corner of 50 Street and 11 Avenue within the confines of the 18th Precinct (MTN). Officers intervened and arrested the perpetrator. EMD responded and transported the victim to Bellevue Hospital and is currently in stable condition. Charges are pending.
The attack happened because people doxed the venue, and directly incited and encouraged violence.
"I kept the location secret. Only people who purchased a ticket were sent the venue address, and the address wasn’t sent out until 5 p.m.
"The email read:
Please DO NOT share this address with anyone, even a friend, and do not post it on social media.
"No one who doxed the venue can claim they didn’t know about ANTIFA’s violent past, and none can claim the event was public.
"Some have said they didn’t “dox” the venue because it was public. That’s a lie. The ticket said on it: “Please DO NOT share this address with anyone, even a friend, and do not post it on social media.” The event was private."
"Someone bought a ticket in order to get the address. They then forwarded the address out, and the dox was amplified on social media." . . .
