Some of the Pai Kias think beating up people isn't against the
law.
They think the are so brave, beat up people.
BUT only defenceless people or smaller sized people.
But when police apear, they flee like rats.
What does this show?
Cowards tryin to be brave? 
Nowasays with rap music, gangsta music, all those violent shows,
people think it's "cool and good to be bad".
