Less Lethal Leone

Tired of the fact that every time you pass by Saint Mark's, the Italian mafia assassinates you with the Shotgun instantly?
Well with this mod you will have a much better chance of surviving when you cross the danger zone.
Anyway, why did Rockstar give them shotguns? If the problem with gta 3 is that, either the weapons are very powerful, or the vehicles are very weak; or both.
