By making broad general assumptions and also missing the entire point? If you want to point out irony or what sounds like is better characterised as hypocrisy, it helps to actually understand the position you are criticising. Then you can critique it correctly and not just throw out banal, meaningless whataboutism, which is what you did.
I take it from your general attitude that you’re not actually curious to understand what the problem we have with the police is. Is that accurate?
