AverageAmericanGuy: Is that really true? You can be charged with trespassing, sure, but can you be convicted of it if you are too incapacitated to control your actions?

At common law, trespass was an intentional crime/tort. You didn't have to *know* you were trespassing, or that your presence in a location was unlawful, but you did have to have gotten to wherever you were intentionally. Again, at common law, voluntary intoxication could be a defense if you were so intoxicated that it negated the 'intent' element of the offense. So for trespass, you'd probably have to be so drunk that you didn't even know where you were. Being so drunk that you don't know you're not supposed to be somewhere probably wouldn't be enough.

Besides, in most jurisdictions the rules for voluntary intoxication have been changed by statute, and can't typically be used as a defense.
