The "Safe neighborhood" or "safe at home" thing...
... is something I hear all the time. Here's my problem with that.
Example 1) I was deployed. My then-wife had gone to the beach with some Marine friends of ours. (I was Navy; we were on a joint base.) She went to the rest room, and on her way there, she encountered a local beating up and choking a woman. My ex, all 5'2" / 103lbs of her, got in the guy's face. The woman, who turned out to be his girlfriend, ran away. The guy started to turn on my ex, when a crowd started to gather, so he backed off.
My ex rejoined our jarhead buddies. They drove to a local biker bar, where they had left a couple of their vehicles, including her 4Runner. They hung out at the bar for a half hour or so, and then my ex drove home, up and over the mountains, and down the other side on the Pali Highway.
Our neighborhood was very nice. We were leasing a 2600 sq ft house, with lanai and mother in law unit; houses nearby were similar. All had yards.
She let the dog (Rott/Shepherd mix) out of the house, and took her to the backyard. Dog started snarling. The local dude and a buddy were climbing over the back fence, coming toward them. They stopped when the dog snarled.
The ex ran inside, retrieved a Beretta 9mm, and ran them off.
Nice neighborhood, but trouble followed her home.
Example 2) My dad's cousin had a lost floral delivery guy show up at her nice place in the woods outside Worcester, MA. Guy wanted to use the phone (pre-cell phone days.) She let him in, but her German Shepherd took an instant dislike to him. He left. She called her husband, who thought it suspicious, and called the cops.
Several patrol cars responded. Turned out a serial rapist had raped four or five women in that area, using the "lost floral deliveryman" routine, complete with fake delivery van.
But she was at home, in a good neighborhood.
Example 3) A friend had moved from San Francisco to Maine, to get away from the city scene. I met her while skiing, as her place in Maine was a B&B near a ski resort, and I stayed there. Nice lady, with a daughter my age. She also had three dogs, an old Rhodesian Ridgeback, a 4yo Golden, and a 1yo Labradoodle or Goldendoodle, can't remember which. One of the reasons she and I hit it off was that I told her to let the dogs loose while I stayed there; she kept them isolated unless she knew the guests were dog-friendly.
She truly believed in the inherent goodness of man. We had several debates over the war in Iraq, the need for self-defense, and similar things - her on the side of man's goodness, mine on the side of taking threats seriously.
I liked her, I liked the dogs, I liked the place, and I made her B&B a regular stay for me when I went skiing.
She was murdered in 2006. An off-season boarder got in a fight with her handyman and killed him while she was out. When she returned, he killed her. When her daughter, the one my age who had moved to Maine to be near her mom, came to check on her, he killed the daughter, and the co-worker who had accompanied the daughter. When the police went out to investigate, he was putting the women in a wood chipper.
SOB also killed all three dogs.
Nice bed and breakfast, home to one victim, and in a very nice, small, resort town in Maine.
My point being, things happen. In my own case, things happened to three people I knew and cared about.
I am armed except when I cannot be.
