There will arise a situation when police or any administrative power to use physical force to control the mob or any crisis situation...
At time the crowd may become more violent or aggressive..
At that time, yo cannot simply stand still...
To control the situation, you have to use physical force..
And the question doesn't leave it clear. I am ALL for force when confronting a criminal who intends to do bodily harm to another person at the time of the offense, be it with stand your ground laws, or basic self defense.
After the criminal is incarcerated however, no, there is no further need for physical violence.
I suppose I can understand how you might need to use physical force to get the criminals into captivity, but after the criminals are contained, there is no need for physical force! Why would we want that? Just being in jail is punishment enough, why beat down a fallen man?
