Never leave the house without.
I am real old & don't need to dance around with some drug crazed reject. During the past 9 years I have had an attempted home invasion & two road rage incidents where I opted to comply with traffic regs & common sense. I could have had my head kicked into pulp, but it did not happen. Stand your ground laws are needed in the face of displayed threat but be very aware of the consequences of "brandishing" a firearm. If possible, try to control the situation to have witnesses.
A near fatal attempted carjacking, by knife stabbing, at a grocery store parking occurred two miles from where we live in peaceful, pleasant, affluent suburbia. This was immediately followed by a fatal & successful carjacking, by knife throat slitting, by the same meth crazy at a motel some two hundred yards distant.
Sad to say, but we are on an increasingly downward pitching slope regarding violent criminal activity driven by drugs & hate. Razor wire, 24/7 watch, & sandbags might be next, like having Viet Congs in the neighborhood. .
