Third vote on no gun. If you are at the point where you are considering violent
counterforce....then the abort/escape option is your best bet. A violent confrontation
with a meth addict is a lose/lose proposition for you.
You are dealing with a meth addict, not a rational person or a state. NOTHING
complicates a violent confrontation (personal or state) more than unpredictability,
virtually guaranteeing non optimal to disastrous outcomes for all concerned.
The time is now for your best (what I call 'stone cold rational') thinking and
analysis. Your children are depending on you----you are the adult in command.
Meth + violence = mortal danger.
