If the poster reframes it as "this is how the police treat you" then I see it being a lot more favorable. If it also took a slightly less hard-line stance, insisting on affirmative consent for instance, it'd also fly better. Overall the message and intent of the poster is clearly a good one, but it's touching an area where every single person is so vastly different on, that nuance MUST be taken into consideration, or it's just going to hit wrong.
