White guy kills black football star.

You would think so. We even had a black political analyst say on TV, "If the jury follows the law, he should be acquitted." But you never know with a jury.

The sheriff said (we have sheriffs down here) "What Gasser (the white guy) said didn't match the evidence." But still, they let Gasser go home, until the blacks (and SJWs) complained.

No, it has everything to do with race. If both guys were white or black, consensus says no arrest would have been made.

That is what all clear thinking people say also. But the black community and the SJWs insisted he be arrested.

As far as legal fees go, this guy was involved in another road rage incident that occurred at the same intersection. He allegedly got out his car and beat up another motorist.

I drove a truck local pickup and delivery for twenty years. Now I have my own business and I drive around all day providing service to my customers. I have never had anything like this happen to me. I get the impression this white guy (Ronald Gasser) is just a hot head looking for trouble. If that is correct, he found it --- again. In that case, he has no one to blame but himself for his troubles. He needs to learn to cool out and be more tolerant of others.

I agree. The courts do too. Gasser's prior criminal history is inadmissible. But I was responding to your comment that, "Too bad he will be up to his eyeballs in legal fees." (Or something like that.)

His legal fees maybe a result of his propensity to handle disagreements with other drivers violently. Nobody disagrees that both Gasser and McKnight were acting foolishly. To play chicken, angrily interact and threaten each other all the way from the GNO bridge to the corner of Behrman Hwy and Holmes is ridiculous. Not to mention the other drivers they endangered. "Okay we get it, he cut you off. Let it go already."

I wouldn't be surprised if Gasser is one of those people who think they own the road. And nobody has the right to drive in front of them.

I think a problem they'll find here and whether it's ruled as total self-defense is determining whether the dead person was armed or not.
If not then I'm slightly puzzled that the other guy's reaction to being yelled at was to open fire. 
I'm also slightly dubious of the idea he was trapped with no chance of escape here.
Has anyone got an image of this intersection?

Also the crime doesn't fit for me. He's being tried for second degree murder? That doesn't make a lot of sense given the circumstances unless Glasser is outright lying about the incident. This seems like voluntary manslaughter not murder.

No. The law says if somebody enters your car in a threatening manner, you have the right to use deadly force. Just like your house. Gasser said McKnight leaned into his car. McKnight's blood was found inside Gasser's car. Leading police to believe it was lawful self-defense.

And Louisiana is a stand your ground state. No lawful requirement to flee a threat.
