Why does it make no sense? My point is that the sort of justice the shooter, and you apparantly, advocate is even harsher than "an eye for an eye", because egging a car, as dangerous as it is, is not on the same level as shooting someone in the chest.
Actually, egg-throwing is potentially more dangerous since one egg landing the right way, and frightening the driver, could create a scenario whereby many are seriously injured and/or killed..
On the other hand, how many people can die from one bullet?
