How to interact with a police officer(s)

Record the interaction. Eliminates potential "he said..she said" scenarios.
Record the interaction, and stream the interaction off-site in real time. (Most smartphones can do this.)
Don't chimp out, 100% chance of a good experience. Like they say if you aren't doing anything wrong act like it.
I know this from personal experience (many)
That's the stupidest thing I have seen in months.
