Where I live if you set off an airborne anything they would bring in SWAT teams to bring you down, so you would be arrested but rescued.

Seriously, though, if done as you describe, benjammin, it could be enough of a nuisance factor to warrant someone calling it in.

Mdinana, I know they've used fireworks to scare birds from runways, right? So the surprise factor would probably work on bigger critters.
