Equipments yes it needs upgrading. Can equip every police wala ??? No because if you do that which means you are declaring a war in yeh city because every rouge criminal then carry a weapon because his enemy (policeman) is carrying one.
These situations ask for strategy
There is no country in the world where every police officers keep an Weapon with them unless you are in a city where crime rates are way too high.
Police is to maintain law and order not to do close combats with rouge criminals.
What we need is more specialised units in every city or state...
