/sarcasmAn assailant pulls a gun or a knife on an intended victim, a CHL for instance, the intended victim must first consider getting away and second be"substantially certain" the assailant is serious about using the gun or knife to do them harm.
I wonder if the police will also have to be "substantially certain" that the bad guy is serious about using the gun or knife before firing to defend themselves? They may get around the duty to retreat, since they are LEOs, but the same logic seems to follow that they would have to be "substantially certain" under this piece of garbage.
