I have no problem calling out what you believe are unjust laws, but the way you did so implies some agreement with those laws from the commentor you were replying to, as well as some responsibility for those laws existing from the police that carry them out.

Calling out a commentor's statement about the police's state of mind at concluding what was undoubtedly a large project for their department doesn't effectively work as a launchpad into a critique of those responsible for the law when done through terse sarcasm that seems to target the wrong responsible parties.
