Impunity. The junior officer is operating illegal operations under a more senior officer that's why he is not phased after the DCIO shows his credentials. Police are cartels nowadays and their territory is well marked out, When a breach is suspected such violent incidences occur. All this bar brawls between police officers happens when other officers try collecting bribes outside their jurisdiction. Bar owner call the local cops he deals with and the result is always violence. A total collapse of an institution.
