Great data to know.
How far away does a runner have to be for you to successfully draw and shoot? You might be surprised at just how much time it takes you to put a bullet on target.
Sergeant Dennis Tueller, of the Salt Lake City Police was able to show that it takes an average shooter 1.5 seconds to draw and fire. He then showed that an assailant running at you (at 14 ft per second) can cover the ground between you and put a knife, or in our case, teeth, into you in that same 1.5 seconds.
Basically, if your weapon is holstered, anything within a twenty one foot circle has the potential to get to you before you can kill it. Kinda scary when you think about it.
