A bunch of open carriers with hunting rifles including the obligatory White Guy in Camo show up and start protesting a prisoner transport outside the station.
The police chief shouts for everyone to grab their vests and confronts the open carrying protesters. "Anyone who so much as touches a weapon is a dead man!" Then she reminds them that subjects in NYC don't have any right to bear arms and basically tells them to "disperse, ye rebels!"
First off, if you're going to confront a bunch of open carriers who have rifles and challenge them to a fast draw competition like its the OK Corral, you may want to throw on more than your soft police vest. That 30-06 deer rifle is going to tear right through any soft vest.
Second, Law and Order couldn't find a scary AR-pattern rifle to use as a prop instead of a deer rifle? Or have we moved on in the anti-gunner NYC imagination to the point where "assault-pattern rifles" simply no longer exist as the "shoulder thing that goes up" has been willed out of existence and we are now moving on to sniper rifles?
Third, I wonder if the people making these shows even realize that in most of America it is perfectly legal to open carry long or handguns. I don't advocate angry political demonstrations while open carrying but I certainly wouldn't expect death threats from the police in, say, Alaska or Virginia.
EDIT: Law and Order, for those unaware, is a TV show. This was a fictional event launched from the mind of some TV show writer, not a real world event with a news story link.
