They really aren’t unless it’s a solid brick/concrete internal wall.
Even Americans, who are surrounded by guns, do not understand just how much a bullet can go through. I don’t expect people who aren’t exposed to guns every day to know.
About 15 years ago, my Minecraft server admin lived in Columbus Ohio, and a stray bullet from a car chase went through his car door and went through his abdomen and seat, and almost went through the opposing door.
My grandparents had a bullet go completely through their house, both exterior walls, and 3 interior walls, before the bullet got lodged in the brick wall of the church across the street.
I myself have attended events that demonstrated the penetration power of pistols, rifles, and shotguns.
Protip for anyone who wants to have something for home decence but is concerned about neighbors, use a shotgun with either target shot or birdshot. Drywall won’t stop it, but it will seriously limit the damage it does to anything on the other side of the wall.





But they get to be super unique to people on the interwebs though, and that’s more important than some random unknown person’s differing abilities.
