I recently asked my girlfriend if she thought it was acceptable to have a gun in the home. While we don't live together I think that it is a very important question for everyone to answer. How many murders have happened because a burglar broke into a house and wasn't expecting anyone to be home and panicked? Fortunately, the NH legislature is looking to make this punishable by death.
I think that every person should have some means of defense in their home. From knives to baseball bats to guns, each person should have a reasonable weapon with which they can protect themselves and their family from invasion.
If burglars knew that going into a home could very reasonably end in injury or death, I would expect there to be fewer break-ins. And that would help me sleep better at night.
