I can tell you that most were stopped by 22's. It was like
that all over the country back then.
Now, that is real world stopping power.
Did the 22 loose all it's power sense then?
Obviously, your experiences were not shared with others in general during that time frame.
If the .22 was considered effective during those days, why didn't LEO agencies issue them at that time?
I think you are projecting your own assumptions and fears of being shot to someone you do not know.
Never 'downplay' a criminal encounter. He may not have the same respect as you do for the .22. Expect the worst. Choose your equipment and train accordingly.
While a .22 may be an effective caliber against someone who is not really determined to hurt you, it may not stop a determined threat to your life, especially if he's wearing a thick, heavy jacket.
Granted, nobody wants to be shot with anything, not a .22 or even a BB gun. But if the bad guys are running on drugs, alcohol or adreneline they may not feel fear or pain from being shot.
Many criminals are not the nostalgic 'down-on-their-luck' hold-up men that you may envision who heist a wallet or two so they can afford a decent meal. Not all of them are stupid and not all will run at the first shot or sign of resistance.
Some criminals today are real sociopaths. They rob and assault and hurt people because they want to. They enjoy doing it.
There are bad guys out there who like doing home invasions, car jackings and even torturing innocent people. They may beat, stab or shoot people to gain 'street creds' and then brag about it to their homies to gain respect.
Some criminals expect resistance and train accordingly. Prison yard videos have shown them practicing their tactics. And I have seen some gang-banger wannabes at my local gun range.
And some violent offenders have been shot, stabbed or beaten before. They often brag about their wounds to police and to each other. It's part of their culture. Many of them are not afraid that their victims may carry a gun. They might not believe you have the will to pull the trigger.
They know that law-abiding, decent people are reluctant to shoot somebody. And if you're carrying a small firearm such as a .22, that might just give them even more confidence. After all, they know they will probably survive a .22 caliber wound, as long as it's not in a vital area. They may decide they can 'take you with them' if you pull the trigger.
Try to get inside the mind of a serious, violent criminal and then ask yourself if you had to fight a few of them off, would you be comfortable with a .22?
I wouldn't.
In my opinion, if you're going to carry a weapon at all, then carry something that has a reputation of stopping a serious, life-threatening attack.
