"I think you need to make a convincing argument that vandalism will be a problem."
I think if the people having shoot outs are so brazen that they can do this and people aren't necessarily reporting them it's not a stretch to think that they will, just for fun, attempt to shoot down a UAV. Wearing a mask or course to protect their identity. Or try to damage it while it sits up on the pole with a rock etc. (Although I guess it could be protected from that fairly easily).
I don't know what thugs do for fun. I don't see why shooting a UAV would be any more fun or wise than taking an axe or chainsaw to a telephone pole to cut the power of a block you intend to commit a crime in. (Plus if you know what the UAVs are for, you know that your shooting will be heard and police can have a very short response time just from that. Add in redundant UAVs that fly higher and faster, you're not getting away.)
Another form of protection: they'd be less likely to shoot at something that shoots back. (Good luck making that legal for a private company though, even if the UAV managed 99% non-lethal accuracy!)
I think UAVs are impractical for other reasons (why not just put cameras everywhere instead of a fewer number of mobile cameras?), but I still don't think they'd be that much more a target for destruction than the electrical grid.

Doesn't have to be the thug shooting it down. Can be a pain in the ass bystander in the hood or someone with a baseball or rock. Have you ever seen kids who throw sneakers up over electrical pole wires in the inner city?

If only there was a device which could be affixed to the barrel of a pistol which could reduce the decibel level associated with the firing process... ;)
Assuming these people did add UAV monitoring (a leap), and assuming a UAV was dispatched to every report of gunfire (another leap), it doesn't matter if the assailants shoot it down because they already know where the gunshot was and, with a decent response time (another leap), officers can be there in minutes.
