I remember the whole trial and know why he got off. Everyone involved said Lewis was involved.
As do I, because I'm in Baltimore and got the story 24/7 from local media (and they were actually pretty damn harsh on him when it broke).
Everyone involved thought Lewis tried to cover his arse when two people in his party were heavily involved in a bar fight where two other people were killed. He was never seriously considered a knife-carrying perp by prosecutors or investigating LE, just a bystander whose friends did some bad shite and who had a lot of money on the line and tried to cover his arse rather than cooperate with the police...a situation many a favorite NFL player could find themselves in, fwiw.
