Geek with a .45 has a nice piece on this, including some very good illustrations. I'd always been told the standard '2 to the body, 1 to the head', with emphasis on the two body shots going to center of mass. I'd wondered about it, especially after reading some accounts of multiple body shots not stopping someone very quickly, but a single shot in the upper body did it. The information Geek provides gives a very good explanation of this.
I will note that the Mozambique Drill(2 to body, one to head if he doesn't fall) has been taught by many, if not most, law enforcement organizations in this country. From what this post shows, I think I'm going to start using the upper body as my main aiming point from now on. It makes sense.
He also links to this article from a newspaper on a poll by the National Association of Chiefs of Police. Real big point from the article:
"NACOP asserts that the public perception of how police view certain issues is based on media coverage, which is not necessarily accurate. When police chiefs and sheriffs are allowed to respond to poll questions anonymously, the politics may be removed from their answers."
Ok, and that means what?
"Gun Control: With regard to private citizens owning firearms for sport or self-defense, 93.6 percent of the respondents supported civilian gun-ownership rights. Ninety-six percent of the police chiefs and sheriffs believe criminals obtain firearms from illegal sources and 92.2 percent revealed they hadn't arrested anyone for violation of the so-called "waiting period" laws. When asked if citizens concealed-weapons permits would reduce violent crime, 63.1 percent said yes."
Now, in the past the International Assoc. of Chiefs of Police has been very loud about wanting more and stricter gun control laws. Many chiefs and commissioners are far more politician than cop, I think especially in this organization. In the National Association the situation seems a bit better, although, as the article notes, these poll results came from people who knew they wouldn't have their name and words reported in the local media. I would wish that these people were more willing to have their opinion known without worrying about the local GFW's wailing and whining, but that's probably futile; they may be more cop than politician, but they like being in that office an awful lot, too.
Yeah, I'm cynical about it.
