[quopte]1.If your going to carry a .22 for defence , you better have the skill and the will to hit your opponent in the head. Then you'd better have the will to go though an ugly criminal /civil trial that has you explaining why you purposely tried to kill vs wound him.
2. The gun, even a .22, does have a "deterrence" or "Oh, Shxxt!" effect, no doubt. I suspect one can put it to offensive use such as pulling it out and displaying it and hoping the "attacker" will pee his pants and run off.
In the state where I live if one uses a firearm like that, he could very well be charged with aggravated assault with a firearm. If convicted, he's going to serve at least one year in prison. If you have the time and distance to pull a weapon and "deter" someone, the law expects you to use that time and distance for other purposes such as pulling the cell phone, hitting "911" or fleeing.[/quote]
Old DNS makes a reasonable point about the better than nothing situation and that he wants to carry a better gun. I certainly and strongly agree with him. One has to limit the argument to the special circumstance of carrying a 22 LR when for whatever reasons that's all you have. The choice is whether you should carry if that is all you have!
If that is case, for whatever reason, then the two posts quote above really don't contribute much.
Let's look at #1 - It ignores the deterrence argument which I know is not appealing to those who want the 'shoot em' option perhaps actually to happen. Most of us would be happy if deterrence occurs. So you would rather throw away deterrence that works most of the time so instead you guarantee that the BG does have his way with you or you have to get into a hand to hand fight or get stabbed? That makes NO sense unless you are just mired into the fantasy of shooting someone. The other point is that you would have to explain that you were just trying to wound someone? Where in God's name did that legal doctrine come from? 22 LRs are clearly seen as instruments of lethal force and if you shoot someone with it, NO one would think that you deliberately choose a wounding weapon. The case will revolve around the legitimacy of your need to fire the gun. Bah.
Now, #2 - again, you don't understand the deterrence argument. If you are in a situation where you can legitimately use lethal force, you deploy the firearm. There is NO necessity to shoot someone. If you can deterr a situation where the use of lethal force was legitimate - that may be for the good. If there was no legitimacy to use lethal force, you don't deploy the gun. This comment is based on a false logic. If you shoot, that depends on how the incident proceeds. The Tacoma mall guy seems to have made the wrong decision by challenging the shooter. However, that is not the doctrine. Every time a civilian or office deploys a gun, you don't have to shoot, you just have to justified to use lethal force. Thus, you won't be charged unless you did not have a good reason.
To return to the point, I would not carry only a 22 based on its performance. I agree with DNS. If however, because of some turn of fate or physical handicap, all I could have or deal with was a 22 - I would carry it.
