Why no Cannons on Police Helicopters?

Where I live, we have the highest automobile theft rate in the US.

Aren't the criminals deterred by the armed citizens?

An armed citizen asleep in his bed does not deter someone from
stealing his car from across the street. This much is obvious. It
*does*, on the other hand, deter a criminal from trying to carjack
him, which carries with it a much higher risk of a non-criminal
getting hurt or killed.

It's entirely analagous to dissuading home-invasion robberies (hot
robberies) in favor of breaking in while the occupants are at work,
which I'd think that most people are in favor of.
