There have always been people who get into law enforcement because it gives them legal cover to act like bullies. The Trump administration has merely made it less necessary for these bullies to adopt some discretion as cover.
This is nothing new in principle, but rather new in scope. Back during the first Trump presidency, the local police attending to local protests had removed or obscured their name plates and badge numbers. Ostensibly this was to prevent reprisals against them, but it also serves the purpose of making it difficult to hold individual officers accountable for misbehavior. The dispute I personally witnessed were amplified by individual police officers who escalated them to physical violence as a pretext for arrest.
This harks back decades to when various governments tried to make it unlawful to record the actions of police. They lost that battle, so now the tactic is to simply be unrecognizable. This has more to do with the Confrontation clause than the Due Process clause.
The notion that a person can be snatched off the street by persons unknown acting under apparent authority of law is not really what I consider proper American values.
