I watched the video of LAPD at Skid Row. The men can't fight. In the past I watched other US police on TV in physical altercations and they don't fight skilled either.
Why is that?
In my country the police learned to fight as small children. Police are proficient and experienced. Police participlate in public competitions and contests.
Police are teaching children and public many fighting skills. Police spend every spare minute practicing a vast array of hand-to-hand and stick/baton fighting techinques. Of course guns, tear gas, automatic machineguns are practiced in addition.
The US police are paid very nice salaries and should practice fighting always. This is to protecting the public from criminals.
