Show me a cop who doesn't park their personal car illegally and I'll stop thinking ACAB. It's not that that's terrible, it's that it's a glaringly visible sign that you believe laws don't apply to you.
I support you in this, but realise the fleas and ticks in the Fediverse are police adjacent. Yet if some thing happens, who is the first they are going to to call, lol.
Not every one is like that, but enough to be ridiculous. As you can surely tell.
