Its a do not rob list.
It could also be a good place for gun thieves to look after they watch a house to make sure no one is home.
“Its a do not rob list.”
And,
It’s a “wait until no one’s home, and ransack the house looking for firearms” list
Oh everybody goes on the “rob list” — later in the article somebody says they would stake out the gun owners first, burglarize them when they go to work. Bootstrap your way up to a free gun, then look at the map again to see where you can put it to use with no resistance. Kinda like burglarizing Home Depot on the way to a construction job.
