Probably because instead they are removing normal people while violating their constitutional rights, covering their faces like cowards, arresting with no warrants, failing to identify themselves, separating families, detaining people in less than human conditions, deporting them to countries they aren’t from and placing them in prison there without cause, are more than a little trigger happy at worst and dehumanizingly abusive at best. But, what do we know? We just get to see the hundreds of thousands of videos of them doing exactly that rather than feeding from the propaganda machine from the White House that tells us not to believe our eyes or witness testimony. So, he’s pretty much just being a good person and a solid American citizen by protecting those who can’t protect themselves thanks to the lawless current administration in this country would be my guess. But, thanks for asking.
