Businesses letting cops know they're not needed

Why am I picturing a hostess greeting people with: "Are you a cop? You have to tell me if you're a cop."

They'd have my business forever
"Show me your dick so I know you're not a cop"
...oh, you meant another kind of hostess? Carry on, then!

I genuinely have no idea.
That's my type

No shirt, no shoes, badge and gun, no service.

Will that even work? With the new ruling allowing warrantless searches? Can I just put one of these up on my front door and LE will just go, "dang, this place looked like a great one to ransack and pillage, but with the sign... Dang."

Depends what you mean by “work”. Being a cop is not a protected class so yeah you can expel one from your private business for any reason or no reason at all.
But if they are investigating a crime, executing a warrant, or any other kind of official business then no this sign doesn’t do shit legally. This place looks like it serves alcohol and is open to the public so there’s no right to privacy from police when holding a liquor license.
That's the fun part... You get/have to bring your own enforcibility

- So when's the Revolution Man? It's a small pizza shop. Not nationwide insurance. It's a fucking pizza shop in Arizona which is right next to the border. There are many Mexican people that live here. These people would want to feel safe. And Welcomeed! Let me repeat, it is a small pizza shop, not nationwide insurance. It's not tone deaf. Or short sighted Sure it is what it is. These piglets don't even follow the law. It's a huge risk. It takes some balls, I think. Especially in this climate. I think you underestimate this drastically. It's not like a wokism and like corporations Virtue signaling. And it's not like some air-headed liberal on Facebook.

That's an open invitation to criminals. Good luck when the cops don't show up

They typically don't until it's all done anyhow. Then they shoot your dog.
- The goons in John Wick have more credibility than cops. I'd love a franchise where it's just John Wick gunning down these IRL goons and knock it off with this thin blue line propaganda horseshit
Cops don't prevent crime. They only respond to it and often commit other crimes in the process
The criminals are the ones being banned from the store
Trick question, cops are criminals

It's a public space. The limitations on search warrants are very low for those.

I just saw my first one if these IRL today at a cafe where I ate lunch. It was only for ICE and not cops in general, but it made me feel good about spending my money there.
