If there was any doubt that Manhattan District Attorney Alvin Bragg was a corrupt law enforcement official who abuses his office to prosecute his political enemies and protect his allies, it was eliminated Thursday when his office dismissed trespassing charges against 30 anti-Israel protesters who had been arrested after occupying a building on the campus of Columbia University.

On the morning of April 30, the protesters, who had already been camping illegally on campus for two weeks, smashed a window on the first floor of the university’s Hamilton Hall, unlocked the door, illegally entered the building, covered the security cameras, and then used wooden tables, chairs, zip ties, and metal chains to barricade themselves inside. Several custodial staffers were trapped inside, too, but they were eventually released.
