Why does it seem like Americans are obsessed over home invasions? Do you have a lot of them?
Constantly see people online talk about "when the robber comes thru my door" or whatever, and some of it is memes, but a lot of it is just people legit discussing what the "best weapon" to fight robbers breaking into your house at night would be - Giving it so much thought as if it is a legitimate concern. So is it? Does it happen a lot?
Sorta tangentially, many American suburban developments are arranged primarily to be as defensible as possible in a way that makes the people living there extremely paranoid. Suburbs often have one or two entrances / exits branching into one looping and some number of non-looping paths. As a result, there will almost never be anyone driving through the suburb without a deliberate reason to be there. Most often, it's because they live there. Neighbors will quickly recognize each other's cars and be able to identify each other's comings and goings. Seeing an unexpected car (or any person of color as many of these spaces are entirely white) will immediately raise questions on the neighborhood snitch app or text group. Also, neighbors are constantly spying on each other because the structure of suburbia highly encourages it. This type of suburban design was created explicitly because of and for the purpose of racist paranoia.
