Bangalore Traffic Police — No Policemen to control the blocked side of road

Being somebody very new to the city. I am first of all very disappointed to see the road arrangements in Bangalore. For eg. On a certain crossing at Inderanagar Nagar all three sides have a flow and the fourth one is temporarily blocked with no signs or a policeman to show the way. And then when one tries to take an exit from that blocked side, you will find police men standing just 50 steps away just trying to ambush vehicles in order to fine them.. So, basically are they gangsters who just want to collect fine money or for that matter money for their pockets. Instead of having their presence on the crossing and guiding traffic, they are 50 steps away waiting for new people like us who just go by google map! to just stop the vehicle and harass.
