tom swift among the diamond makers

 For active self protection, I am going to talk about distance. So there was this police officer ad he almost died by a knifing this guy was mentally sick and it was a big problem because the police officer shot him because he had a knife but that's not what I want to talk about it was what he did to protect himself he kept his distance he did not get up straight to the door he stayed at the bottom of the steps and when the guy came out and the officer saw the knife he was able to get away with all haste and get that one shot away in like five seconds it was also a perfect shot right into the center body mass.
