In the current climate in the US, there will be lawyers eager to find any possible grounds to file a lawsuit for stupendous amounts because the cop looked at someone wrong, and hurt their fragile self-esteem (I exaggerate, slightly). That's probably going to make an environment where police cannot operate effectively. Yes, they'd be careful not to step across the line. But they'd have to give no grounds for a lawyer looking for a payday to even be able to
claim that they had stepped across the line.
The current abuses are horrible. But cops fearful of their own shadow is not a better outcome for society.
