This is an animated video directed by Joseph Gordon-Levitt with music from the Gregory Brothers. You don't have to give up your camera or recording device and you don't have to delete what you recorded.
You want to check out the full post; it contains information about what to do if a police officer tries to detain you or confiscate your property. There are ways of speaking to law enforcement that can possible extend your life span.
I make no promises. Not as crazy as it has been these past few months.
