Kirk...I am so very, very sorry about the agent and his family. That was horrible. I imagine the wife lived in constant fear of getting "that visit," and to get it the way she must have gotten it...she's probably going to torture herself for the rest of her life with "if only I had done something different."
The first time I was driving home with my kids and passed up the private drive and kept going, they went "uh...Mom? You missed our driveway." I calmly said "no, I didn't miss it. That car has been behind us for several turns and I'm not about to lead him to where we live. Don't turn around, just sit there." Like most times, the car was simply going to a house farther up the street. I always drove right past the driveway, though, and always kept an eye in the rearview mirror. Perhaps excessively paranoid, but as I told the kids, you only had to be wrong once.
This woman wasn't wrong. A meth addict was following the family of a narcotics officer.
PD...I've read a lot of books by different authors that all said the same thing. Handguns are useless for most situations/people from a distance of more than 10 feet. All that "magic shooting" in movies is just that: movie magic. (Like the handguns that seem to have clips of 200 bullets in them.) Lawrence Block writes a series about a hit man who, when he intends to use a gun, never intends to do anything more than shove it into the victims body and pull the trigger. The character always says he couldn't hit the broad side of a barn otherwise. (I know I'm speaking here about fictional characters.)
