A paintball gun might not invoke the federal government to hunt you down; an over-powered laser absolutely will. The FAA has a very low tolerance for that sort of thing. Do not ever, ever, ever use lasers in open air that are capable of damaging the human retina without the appropriate licenses. The last thing cities need right now is another federal agency going on a witchhunt. Firing eye-damaging lasers into the air would just serve them that excuse on a silvered platter.
The CCDs in cameras can be damaged with low-power lasers, or so I thought. No need for anything crazy. And the FAA won't become involved unless you're pointing them skyward. Pointing them across the street, or anywhere not visible from the air isn't going to sic federal agencies on you.

The point here is that 'skyward' is where the laser's beam goes when you're trying to aim it at a camera up on a pole. It's practically impossible to point a non-fixed position laser at something a non-trivial distance higher than you without spilling a large amount of laser beam into whatever happens to be behind your intended target; which is very often the sky.
