Always stay vigilant. If someone approaches you, watch their hands and eyes and prepare yourself. If they look the least bit nervous, that's an alarm. If they move too fast, give yourself space. I don't like anyone making me play defense.

There are videos and evidence of "bad guy" scenarios, with a knife, taking less than 2 seconds to cover 21-feet. 

21-foot Rule...being able to draw and shoot and engage a target at 7 yards in 1½ to 2 seconds...

So, "situational awareness" within that distance is already problematic.

  Any clown facing a cop, and threatening with a knife within 50 feet, should expect to be ventilated !
