You already had a huge scandal in the UK with the police being afraid to break pedophile rings in several cities because they thought they'd be accused of racism. Condemning them for being calm, but not impossibly professional while dealing with paranoid people will surely motivate them even more and ensure maximum efficiency. Comparing them in a critical way with the US police which is regularly killing people likewise.

And if anyone arguing against the approach you support is apparently ignorant or provoking your disgust, I think I'd rather let you focus on fighting this good fight and dealing with its Brexit consequence.
