One, is that if even 1% aren't, those 1% can cause untold damage to your life. We're usually pretty bad at judging risk, so many people won't accept "a very low chance of a very big problem" for the same reason many people will accept "a very low chance of a very big reward" and play the lottery.

The second is more disconcerting to me; all too frequently I see people assume that when someone had a bad interaction with the police, they must have done 'something wrong' to be interacting with them in the first place. Either we believe police are eminently approachable, or we believe that someone interacting with the police "must have done something to deserve it". We can't have it both ways.
