You mean the US where in some areas everybody and his dog carries a gun the way most of us carry wallets? As compared to most countries where guns are rare, strictly regulated, and where carrying them is strictly prohibited except for on-duty police officers?
You mean the US, where this old guy fatally shot a man for texting in a movie theater – and was just acquitted? Or where this guy fatally shot a young man for playing music too loud?
The US had 19,384 firearm homicides in 2020. The number of firearm homicides in the United Kingdom in the same period: 30.
Yes, I’d seriously think you might be shot for this. Especially in the US.
