Are you seriously saying if someone does 30-35 mph in a residential neighborhood that they should be shot? I do not advocate reckless driving. You drive to the conditions. It is just conditions allow driving at higher speeds that are posted. If there are kids in the streets playing you should slow down. I have to in my neighborhood. However when these kids get to teen and 18 years old. They like to smoke their tires, which annoy me considerably. Should I shoot them? Call the police for someone being annoying? These teens do grow out of it.
Exactly the mentality that causes accidents. It's never the kid you see that gets hit. You should always assume there are kids YOU DON'T SEE playing on any residential street. So, on a residential street there is never an "IF" kids are playing, it an "ALWAYS" kids are playing.
