has me reaching into their pocket knowingly
In this case you’d be performing an illegal search and should not have your hands in their pockets. How could they know you were going to illegally search them? If they’re a law abiding citizen with razors in their pockets and you illegally search them, those cuts are on you.
Now, as for how this would play out in front of obviously corrupt police institutions — yeah you’d likely have evidence planted on you for pulling a stunt like this.
I think my favorite variant of this is: “Hatred is like swallowing poison and expecting someone else to die.”
