The guard can be seen holding another rifle which has no magazine. He renders the weapon safe after retrieving it. He later returned the guns to police.
Aside from maintaining enough distance to not get hit, closing the distance against a blunt weapon is the best option. Moving into a clinch removes most of the advantages for the weapon.
Conversely, stepping away keeps you at the effective range which is very bad. The victim here was slow to respond and took a lot of damage, but ended up in a better position toward the end of the video where it ends without a satisfying conclusion. The aggressor even threw away the stick when he realised that it may now be used against him.
Seeing police in retreat, the crowd mistakes this for a lack of will to fight. Once a police officer falls and has their gun taken, his colleagues return and now have a justification for use of deadly force.
The man holding the baton made some errors:
- Allowed his opponent to close the distance when he had a tool which needs more range.
- Range can be managed by movement – he’s completely stationary.
- Flat posture, straight back, very likely standing with knees locked straight, does not appear to be in any kind of stance which would prepare him to respond in the split second required to move, defend or attack. His opponent constantly adjusts.
- Allowed opponent to grip his wrist. Difficult to swing baton effectively when grappling starts. The grip even from this position may allow opponent to stay off-centre when the baton swing comes.
- Furtive glance made by opponent is a huge warning sign. He has already decided to attack at this point and is looking for witnesses, other enemies or allies which may factor in to his decision to go ahead.
- Even if he decided to use the baton, it’s a poor weapon. Law enforcement use this as a method of pain compliance, and often need to move to other methods when it fails. Striking the legs is unlikely to instantly shatter kneecaps unless you’re very lucky/unlucky to hit that spot. You’re only starting the fight, not ending it. Swinging to the head would be a different matter.
- Compare the above (pain compliance) to the punches thrown to the head (incapacitation).
Baton man seems to think intimidation is enough to keep him safe. The baton is like some kind of force field, everything else can be ignored.
From this position, when would he decide to use it? Once the fighting starts? Too late, too close. When the man fails to step back? This may be considered unjustified assault. Baton man then made a threat to seriously harm, which prompted an aggressive response. He put himself in a situation which is very difficult to win.
Rather than reaching for the knife when it is drawn as many people tend to do, this security guard punches the man, and as they go to the ground he and controls the hand holding the knife. He extends the hand away from the body which prevents the man from reaching for it with the other hand. Bystanders step in and assist. Excellent instincts.
