I guess calling the police just wasn't an option in that situation, DUmmies?
Hey, I'm all for use of deadly force, but one little phrase sticks in my mind when reciting the definition (still from memory, over 25 years after I learned the definition in the military):
"WHEN ALL LESSER MEANS HAVE BEEN FAILED OR CANNOT REASONABLY BE EMPLOYED."
IOW, DUmmies, she shot her brother because she's either 1--psycho, 2--was tanked, 3--both 1 and 2. Actions have consequences--who the **** knew?
