Stand Your Ground? Texas man kills teacher over noise complaint

[AnotherMcIntosh]

161. He is not "my boy Rodriguez." In modern America we don't use such phrases.

If you really want an answer to your first question, and if you want me to speculate based upon what was on the video,
(1) Both gun owners apparently had confrontations in the past with each other over noise.
(2) Rodriguez complained to the police in the past with respect to the noise.
(3) The police did not resolve the problem.
(4) After Rodriguez measured the amount of the noise near the street with a meter of some sort and telephone the police, a police dispatcher telephoned the other gun owner and told that gun owner that Rodriguez had complained about the noise again.
(5) The noise makers decided to drive to where Rodriguez was in order to have a confrontation with him.
(6) The video shows that the physical education teacher (or former physical education teacher) had a bulge under his T-shirt.
(7) One of the shootees said that he was going to go back to his house to get his gun, which, if he meant a rifle, would have been a better choice over a hand gun.
(8) The other two shootees did not say that they had to return to their homes to get their guns.

With respect to your last question, I would not have a party in Texas.
