I was thinking the same. You can’t shoot just because you think you see something or someone. Be sure of your target and what’s behind it.
My parents always had a rule, don’t go onto neighbors property to play.... unless it is with the neighbors children you are playing. In my head I can still hear, “Don’t be stupid” trespassing will get you shot. Back then of course it was with a 12 guage loaded with bird shot or rock salt. Yes, in 2023 you still need to be mindful of boundaries.
With that said, you shouldn’t be shooting at shadows. If you are that paranoid or blind, your children should have long ago removed dangerous things from your reach. See? This is the proper place for a sawed off shotgun. Kills you dead if within a few feet, like in a house, but you can fire it off at kids in the shadows and have them jump out of their skin, but go home with a story.
