I took the juvenile court reports and compared them with the public school enrollment records. It came out to about 9.6%. Mostly age 12 and up. It is a high figure and that's the concern. I think most people would be shocked if they looked into the numbers in their area. Your public officials may not make it convenient for you to find the numbers, either, and don't particularly like people asking too many questions.
Where can you find out how a judge ruled in a particular juvenile case and why? It's protected from disclosure to protect the juvenile's future. So a bad judge can make one bad decision after another unless somebody gets mad enough to go public about the judge's handling of a situation in a particular case. If you don't succeed in getting the judge ousted, then woe is you if you ever find yourself before that judge in another case.
Unless it has been changed by statute in your area, the common law rule is that you can use deadly force only to protect your life or the life of another person. Deadly force cannot be used to protect a mere property interest. The application of the rule largely depends on local prosecutorial discretion. If your shoot and there's a body to account for, you might encounter a different attitude and certainly many more questions.
In the major metro area about 60 miles from here, the prosecutor presents self defense shootings to the grand jury and let's them decide whether it was self defense or not. Someone might have been perfectly justified in shooting, but whether he ends up being criminally prosecuted for it depends on the outcome of the grand jury deciding if there is reason to believe a crime was committed. That's not a comfortable position to be in.
I agree there are places where common sense says a person is taking chances going on another person's property at night uninvited which deters some people from taking those chances. But as soon as somebody's kid gets shot, his family will all say he was a saint, and the shooter needs prosecuting.
But it comes back to this. If these families were raising their kids with appropriate self-discipline, the families, the kids and the rest of us would be far better off.
