Preparation begins with choosing an area to live where you WONT feel the need to live in fear. Preparation doesnt begin after a poor choice of neighborhoods, thats called an "afterthought".
TOS.
Not everybody desires...or can afford...to live in an upscale gated community like yours.
Not everyobody is comfortable with the idea of entrusting the responsibility for their personal safety in the hands of the police department.
When you call "911" for a crime in progress, you are basically requesting assistance from an emergency responder who is armed with a gun. If the nature of the crime is such that it requires an immediate armed response, doesnt it make sense for you as the potential victim to already be armed?
Put another way...if you rely on the fire department to protect your home from burning down or provide immediate medical assistance, does that mean that you dont need to keep a fire extinguisher and a first aid kit at home?
If you wish to sit in your gated community and rely upon armed responders from a nanny-state government to protect you, that is your choice and I respect it. Please grant the same respect to those of us who do NOT choose to live in gated communities or rely upon a nanny-state government for our personal security.
