You Know Who Nick Stahl Is Now That He Was Pinched for Busting One in a Porn Shop [VIDEO]

Nick Stahl was reported missing a few times earlier this year, and now we know where he may have been hiding: a private porn booth.

The troubled 'Terminator 3' star was arrested Thursday night for committing a lewd act (read: rubbing one out) in a porn shop. Dude, that's like reading books at Barnes & Noble and putting them back. Only, you know, a lot more gross.

Stahl was taken into custody around 6 p.m. when Los Angeles undercover vice officers were doing a "routine check" of the adult store, which is weird in itself. (Are they judging you for your taste in movies? Do they expect to not find things like this happening?)

The actor was released a few hours later and wandered off into the darkness, giving curt but polite responses to a TMZ cameraman following him around.

Word to the wise? Get a laptop and a locked door in your own house.

And a word to the taxpayers of Los Angeles: Aren't you glad your tax dollars are being used for cops to address truly dangerous situations like this and not something silly like gang violence?
