Screech from Saved by the Bell got arrested up here right near my town. The headline that shows up all around the social media says it's because of the switchblade he had.
What they DON'T mention until you actually click through for more, is the fact that he stabbed someone in a barfight and fled the scene. Quite a world of difference between assault and "You had something we said not to have".
For reference, carriage of arms without a license (anything, even a 1.75" blade pocketknife, can still be counted as a concealed weapon if the police decide they don't like you) is a misdemeanor, and I believe that so is possession of a switchblade, because WI is still stuck in the 50s where only gangsters and greasers have switchblades and banning them turns them into harmless law abiding citizens.
