You ever notice, when someone does something stupid or illegal. The answer is always, it's someone or something else's fault. "The drink made me do it!" "I wouldn't have killed him if the gun didn't go off, so it was the gun makers fault!", "I wouldn't have robbed them, but they had money, and I didn't, society should have made me a rich man!"
The judge should throw the case out as a frivolous lawsuit, and government should refuse to pay the jerks medical bills.
