There were intense security protocols in place Monday ahead of the New York Knicks’ first NBA Finals game at Madison Square Garden since 1999 due to President Donald Trump’s attendance. Only ticketed fans and those with business inside the immediate area of the stadium could frequent a designated radius around the arena, marked by a steel fence, with limited access points and restrictions on what attendees could bring to the game.The President will not be in attendance for Wednesday’s Game 4, so the team is bringing back its watch party outside the Garden. Yet it will feature a similar security perimeter to Game 3 — which will close all traffic from 29th to 35th Streets between 6th and 8th Avenues — after a series of arrests following the Knicks’ 115-111 Game 3 defeat to the San Antonio Spurs.That led Madison Square Garden Sports Corporation, which owns the Knicks, to issue a statement Tuesday calling New York City Police Department commissioner Jessica Tisch and Mayor Zohran Mamdani the city’s “biggest party poopers” for retaining those restrictions around the Garden.“The complete closing of areas around MSG is going to affect not only the celebration but also all the small businesses that rely on Garden fans for their livelihood,” the statement said.With much of the focus on the game itself, we spent Game 3 at one of the local businesses, O’Brien’s Bar and Grill, located on 31st Street directly across from the Garden, to see the impact of the security perimeter on what should have been one of the busiest nights ever for the establishment.
