For example, if an insecure cop tries to tell you that you’re violating his civil liberties, you might respond by saying “Officer, with all due respect, state law only requires permission from one party in a conversation. I don’t need your permission to record so long as I’m not interfering with your work.”
If you live in one of the 12 all party record states, you might say something like “Officer, I’m familiar with the law, but the courts have ruled that it doesn’t apply to recording on-duty police.”
If protective service officers harass you while filming on federal property, you may remind them of a recently issued directive informing them that there’s no prohibition against public photography at federal buildings.
“Stand back.” If you’re approaching the scene of an investigation or an accident, police will likely order you to move back. Depending on the circumstances, you might become involved in an intense negotiation to determine the “appropriate” distance you need to stand back to avoid “interfering” with their work.
If you feel you’re already standing at a reasonable distance, you may say something like, “Officer, I have a right to be here. I’m filming for documentation purposes and not interfering with your work.” It’s then up to you to decide how far back you’re willing to stand to avoid arrest.
