This is going to get far to philosophical, and this is probably more about society than this actual event. But why is it, that when given a choice, most people want to be the aggressor, even if they don't really need to be.
I volunteered at a shelter for six years, with people with all kinds of rap sheets. Because of that, it kinda makes me a little sick each time I hear someone say "They choose to break in to someones house, therefore they have to be ready to face the consequences".
People, especially those from "Christian" backgrounds (like myself), are SO quick to judge. There is only one person who came to judge the quick and the dead, and that's God. This is in no way a religious debate, but what in the world gives some old man the right to shoot someone IN THE BACK running from a crime scene?
And believe me, these people who just randomly "break into homes", aren't naturally evil people. I personally got to see the places a lot of these people came from. Most, from a single parent home, sexually or physically abused, on drugs, trying to get by the ONLY way they ever saw.
It's real easy for all of us in our white, upper middle class lives to think that "stealing" is such a terrible act. But remember, you weren't watching your Mom getting beaten up, while your alcoholic dad was forcing her to turn tricks for cash. For a lot of these people. That's what they saw. For year after year after year.
All of them? Absolutely not. But like I said, who is this guy to be the person to judge them?
If that was considered "legal", then the old coot better head to Houston and sit outside any big business, where a middle age white man rips his clients off by stealing from THEM. Only difference is, he does it through laundering, extortion, insider trading, etc. Lucky for him, he was smart enough and lucky enough to go to college.
At least the poor Mexican immigrant never had a chance.
So when you see Mr. White business man running towards his Mercedes, I bet you won't find any old men gunning him down...
