Holding a gun to someone at close range means things can get very complicated very quickly. Within arm’s reach usually isn’t a good range.
This man does not have many skills; but speed, distance management, movement and positioning allow him to use his right hand to great effect against men who possess even less skills than he does.
Pawn shop owner feigns compliance, moves to cover and counter-ambushes robbers.
Two men argue with two security guards. Another guard grabs one of the men around the neck from behind. As the other man looks back and is distracted, a security guard standing in front of him punches.
The guards flanked and overwhelmed the two men. Human only have eyes in one side of their head, and a split second of distraction is all that is needed to land a punch undefended.
Most people tend to overestimate their fighting ability. This man is off the mark further than most when he is surrounded by 5 youths (including the one operating the camera). He initiates the violence (flicks a cigarette at one and pushes another) but takes no appropriate action – allows himself to be surrounded, does not move, does not position himself correctly or attempt to isolate and incapacitate his opponents. He appears to falsely assume these youths will cower and back off.
In this case, it appears that baton strikes had no effect on the suspect who continued to resist. Grappling alone would have had the same result with less harm.
The robbers started this with an advantage of initiative, numbers, preparation and mental preparedness. This is why the ambush is the most effective form of attack. If the shop owner were to react at this time, he would lose the majority of the time.
This shop owner feigns submission, waiting until the robbers are no longer focused on him and draws to fire when they are at their most vulnerable. This is a counter-ambush.
The exact circumstances of this situation are uncertain, but it appears that the white male may have had someone kind of disagreement with the very short black male. The other two much larger black males then attacked him in a fairly excessive way.
Engaging in confrontations with unknown persons always carries this kind of risk. It’s doubtful the white male would have ended up in this situation if he knew the smaller man had friends.
