Maybe they think we should get rid of all those multi-ton killing machines known as automobiles as well. And baseball bats, and golf clubs, and sharp rocks... After all, there is no Constitutional protection for owning a baseball bat now is there?
Automobiles are under far more control than firearms in some respects. You cannot legally drive one without passing tests showing that you can control it and that you understand the rules of the road. Not so with firearms no proficiency tests are required, no vision tests. You do not even have to know which end the bullet comes out of to buy weapons capable of immense damage.
And Nope there is no constitutional guarantee of owning a baseball bat.
BTW you lie about 186 as well as 188.
