Some great points. Not only is our military so heavily geared, but they're now giving surplus military equipment to police. I would say if the police are allowed to have/use than I am within my right to have something equally as powerful as them to protect myself and my family from corruption.
I don't like limits or reductions genrally as a law. They make poor laws and here's why. What makes a weapon a semi-automatic/automatic weapon by definition? Where do you draw that line and who decides. Same goes with ammunition, how much is too much? What's too much to me who owns no guns maybe different from recreational shooters or hunters.
Look at what happened when they tried to ban alcohol. I don't understand why people think banning guns will be different.
