Technically speaking, you can even shoot people for spray-painting grafitti after dark (under the "criminal mischief" statute), but most folks consider that overreacting.

Well, I suppose it would all depend on how tasteful their art work is.

" but most folks consider that overreacting".
Well, maybe most folks in Massachuschetts or jersey.
Here in Texas, if a person tresspasses after dark, no intent must be proven by the property owner that shoots them. We even allow the county coroner to retrieve the carcass. Overreacting is when ya' run 'em through the whisperchipper, and bait yer catfish hole. That is just wrong. If ya caint noodle or flag your catfish without cut bait, ya be a sissy.
