Mandate to buy gun liability insurance?

[davester]

There's nothing in the constitution that says that there is a right to own a weapon for personal purposes (sport, self-defense, etc.). I agree that there should be no burdens (monetary or otherwise) on the right of the people (not necessarily individuals) to bear arms in support of a well-regulated militia. However, the almost completely unregulated ownership of guns for all sorts of uses having nothing to do with this purpose is not a constitutional right. Why is this difficult to understand?
