traffic police in general try their best, its the people who should control their urge and stop taking vehicles on foot paths, over taking and blocking ways, wrong parking, no concern for ambulance, if people do what they are expected police can do their job, and even people walking on ROADS SHOULD KNOW " WALK ON RIGHT SIDE OF ROAD IF THERE IS NO FOOT PATH" to avoid accidents, this I learn when I was in 1st standard.
