I've always had a soft spot for the wicked Trespassers William. It must have been a hard life to drive him to such (unspecified) naughtiness.
In England, at least, we politely request that trespasses be forgiven. (As I recall, in Scotland we ask to be let off our debts. No wonder the country went bust.)
So let's extend that principle of forgiveness to him and his American namesake, Trespassers Will B. Prosecuted. (In England, of course, trespass is a tort: a civil offence for which one sues, not prosecutes.)
