The Tueller Drill:
"A common test of handgun skill was to start with one’s hands at shoulder level with a holstered gun and place two shots on a target 7 yards away within 1.5 seconds. Typically, those trained with handguns can complete the drill in 1.3–1.4 seconds, although some have managed the task in less than one second.
Sgt. Tueller wondered how quickly an attacker with a knife could cover those same 21 feet. So he measured as volunteers raced to stab the target. He determined that it could be done in 1.5 seconds. "
Thus what has become known as the Tueller Drill proved that if your weapon is not in your hand, you are in danger from a rushing criminal with a knife twenty one feet away. Most people covered the twenty one feet in one and one half seconds for an average speed of fourteen feet / second.
If you are not prepared for a rush on your position from forty-two feet or seventy feet, because it is too far away to worry about, you are mistaken. Forty-two feet can be crossed in three seconds and seventy feet in five to six seconds.
One of the common methods of home invasion happening in our cities is the rush-in. The criminal hides nearby until the split second the victim opens her door, then rushes out of hiding and slams into the victim, pushing her through the door which is quickly closed. This type of attack also happens at atm machines.
But what if you do have a gun in your hands and you are not caught by surprise, which you probably will.
When do you shoot? At what distance?
And what if you hit him once/twice/three times?
Will the armed opponent stop? Or will his adrenaline carry him over to you and stab you several times while you hold your smoking gun?
