NYS already banned suppressors for the plebes. Only cops can buy them in NYS. And its highly unlikely they had a NYC permit, for carry, only cops get easy NYC permits, and also C execs like this guy who pays off the right people, in the correct amounts.
So, this means, it must have been a cop that did the shooting. Because it could have been an oligarch with the legal gun, but they couldn’t get a suppressor in NYS.
NYS has already done this, by and large.
