Yes! From the MTV link
"Apparently it's 100% legal to own a ***** cannon, but police arrested Malta for menacing and harassment after "[w]e had reports from people that had heard the cannon go off," some of them reportedly miles away.
The local sheriff wouldn't say what drove Malta to this alleged barrage, only calling it "a civil matter," adding, "I don't recall, during my 34-year career, taking a cannon" until now.
Somewhat disappointingly, police claim that Malta wasn't firing cannonballs, just the cannon equivalent of blanks. If he had, though, the National Cannon Association would probably blame the neighbors for not owning their own howitzers for self-defense"
That looks like it was written for a JREF thread about guns!
