You are mis-representing the incidend.
The Japanese student had gone to the front door and then had gone around to a side door, scaring the wife. She screamed and yelled for her husband. he came and the student rapidily approached him, wildly waving his arms. When he did not stop he was shot and the grand jury no-billed.
It was in the paper that it was known to the students friends that he would wildly wave his arms around people.
Last thing I saw on this particular issue the Louisiana state legislature refused to change the law.
Hey, what can I say about these guys ~ they've voted in nutcase after nutcase after criminal after criminal for years ~ why should their law be any different?
