My wife and I have been quite scared lately. There has been a rash of burglaries and robberies in our neighborhood lately and some have involved violence against the home owners!
Good reason to be scared.  What steps are you both taking to increase security?
We have an alarm system with cameras and I also have a gun for self defense.  I have to protect my wife and daughter!
A good sound plan.  You're right it is a father's responsibility to protect his family.
