The right of keep arms

The right of if citizens should keep guns is usually a controversial issue.  According to the Declaration of Independence, it said people have the rights to keep arms.  But, I don't think it wants to promote people using guns exactly.  Although, People need to protect themselves, and they can choose to support the government or not.  For a long time, the increasing crime rate shows that it is influenced.  It's a ambitious problem to people.
