911: "Hello, state police, what's your emergency?"

Me: "I'd like to report a drunk driver on the Pike. They are driving in both lanes and nearly ran me off the road"

911: "Do you have a description of the vehicle?"

Me: "Crown Vic with state license plate # 9"

911: "Mmhm, we'll get right on that"

/me drives under posted speed limit the rest of the way home to avoid retribution.

Maybe someone can correct me or give a little more details, but I'm under the impression many communities have tried to make recording police officers illegal.

Communities aren't doing this. Police departments are using warped interpretations of wiretapping laws or just outright lying to go after people who film them. The will of the public is not considered.
