Protect from what?
I've suddently found out I'm old and weaker. I can no longer count on disarming or maiming any assailant that enters the 25 ft area around, me with just my hands and body.
I've survived an attempted robbery and faced down some situations.
We have had our home invaded and I couldn't reach my new weapon becaause it was too far under the bed.
Macho man doesn't need a weapon until he does. I'll never tell someone they don't need a weapon. Things changing unfortuantely and I can't afford a LEO on the payroll to be by our side.
I hope I never need one again.
having one and knowing how and when to use it means you may never have to use it.
As far as Laws I can do nothing about them. Life and liberty come first.
