Senate Minority Leader Chuck Schumer (File)It is crunch time in Washington. With a potential government shutdown set to trigger Friday night, Senate Minority Leader Chuck Schumer has drawn a line in the sand. First, he wants to stop “roving patrols”—where officers drive through neighborhoods—and require tighter warrant rules before agents can enter homes. Finally, he wants to ban officers from wearing masks while making body cameras and proper identification mandatory. These demands come in the wake of the fatal shooting of Alex Pretti by Border Patrol agents in Minneapolis, an event that upended what was supposed to be a straightforward vote.
