By the same token armed police probably shouldn't go anywhere like that without a psychiatric first-responder. I'm pretty sure de-funding simply means allocating less funds towards conventional police so we can put money into something like the first-responder I mentioned.
I'd also like to see police cars being outfitted with surveillance drones that take off and hover above the scene of an arrest to provide a record from that perspective.
How much are you prepared to spend. I'm sure the police would like more drones as well.
