All politics is local. The law where I live clearly says one thing: City discharge firearm is allowed if: "9. In self-defense or defense of another person against an animal attack if a reasonable person would believe that deadly physical force against the animal is immediately necessary and reasonable under the circumstances to protect oneself or the other person."
The problem is that in my town in Arizona, where this law and its exception 9 applies, a person can expect to spend a night in jail when his case clearly falls under this exception.
"Dogs again", this topic comes up for me regularly, 180 miles walking per month in nice single family residential neighborhoods. Sunday morning, July 10th, yet again. I have only one ankle to support a full one-half of my body for the rest of my life, and I will defend it to prevent any injury to it or to any proximal or distal portion of my body; no matter how unimportant anyone thinks that portion of my body is to them. By the way, when I phoned the police on Sunday morning to report the charging dog, the desk person could not hear me due to very strong wind. She repeated this three times while I was attempting to phone in my report. I blurted out "That is why I don't carry pepper spray!"
I don't have time to mess with (illegal?) warning shots. I don't have time to try a psychological stop. Humans and dogs regularly ignore sensory irritants to acquire the target.
Here is an analogy: Alcohol and tobacco are to dangerous drugs as dogs are to dangerous animals. Alcohol and tobacco are socially accepted dangerous drugs, and dogs are socially accepted dangerous animals. But, when I walk down the street, alcohol and tobacco do not run up to me with deadly intent.
This mornings news, dead baby, dog owner sings same old song: "He was always so nice and friendly with the baby. We don't know what could have gotten into him."
Cars, trucks, doorknobs, bed sheets, knives, guns, handkerchiefs, gasoline and drugs are all inanimate objects. They do not exhibit any unpredictable deadly behavior. Someones' at-large dog is on a much higher danger level. If it gets within 21 feet of me, too fast, too furious, focusing all of its obvious rage at me, when I have a very few tenths of a second left to stop the threat, I will.
