Would get no complaints from me if we had snipers on supermarket roofs. Take out the scum parking without need in disabled spaces with head shots. Kneecap for the mother and child bay if no child. Earlobe if child looks a bit old.
Could even give daily quotas that could be made up of those playing music in vehicle too loudly, overweight people, garishly dressed, mums in pyjamas
No need for this to be done be full policemen as could use Serco to ensure private sector efficiency
