This is why I teach my children never to speak to police officers, to avoid them as much as possible, and to leave the area should they become visibly present.
And I live in Canada; when I travel to the USA on business I stay in the hotel or the venue and restrict my traveling as much as possible. I don't fear the citizens, I fear the police.
