Not sure what a local cop has to do with a federal agency, what they are supposed to be doing, or where you are getting your data, but if the general population is “speaking out” at a lesser rate than local cops, then what would that say?

There are so many good arguments against law enforcement policies in the USA. This is just a cargo cult version of those arguments.

what they are supposed to be doing

When a federal cop commits a local crime, like for example a murder caught on camera, then it is the local police departments duty to investigate, and the local DA’s duty to prosecute.

When they refuse to investigate and prosecute due to federal pressure, that is an abdication of their duties.
