Dustin Diamond -- Convicted in Stabbing Case

Dustin Diamond was convicted Friday in the case where he stabbed a guy in a bar, but in a way it's really a victory for him.

Diamond was convicted of 2 misdemeanors but acquitted of the far more serious felonies.

As TMZ reported, Diamond, who was with his girlfriend, stabbed a man in the Wisconsin bar last XMAS, but he claimed self defense. Diamond testified, "I felt like we were being set up for antagonistic purposes." The actor who famously played Screech claimed he was merely waiving a pocket knife around to fend off aggressors, never intending to stab anyone.

The guy he stabbed didn't even know he was cut until after he left the bar.

Diamond was convicted of carrying a concealed weapon and disorderly conduct. Worst case scenario is a 9 month jail sentence.
