I am a free speech absolutist. I may disagree with what you say, but I will fight to the death for your right to say what you feel. The first amendment to the US Constitution doesn't have any restrictions, but in the 1920's the US Supreme Court ruled that the end of free expression is your right to yell "FIRE!!" in a crowded theater.
Since time immemorial, there are three offenses that civilized society will not tolerate, and one of those is the unsanctioned murder of another individual. The penalty for this offense ranges from exile to the death penalty.
It's too early for Luigi to say what validation he felt he had in shooting a man in the back. Shooting someone in the back instantly negates a self defense justification. Law school graduates might want to prosecute the case, but it's entirely possible that Luigi's lawyers will mount a difficult to overcome defense based on Luigi's looks alone.
I did an internship in a District Attorney's office. 99% of the cases we accepted were slam dunks, that, even at trial, only took three hours to resolve. One attempted murder case I sat in on, the suspect managed to get one of those ultra liberal west coast lawyers that took a three hour trial and stretched it to thirty six hours with the most convoluted throwing spaghetti at the wall defenses. Despite the valiant defense, the suspect was found guilty and sentenced to 99 years. The judge then had the courtroom cleared, except for the defense and prosecution teams. The judge then issued a blistering take down of the defense attorney that ended with a pledge by the judge to begin a disbarment investigation.
It's way too early for Luigi's case to indicate a direction, but there is no doubt in my mind, that as I type this, lonely women are taking love letters, tonight, to the post office with Luigi's name on the front of the envelope.
