I have had many arguments with people over the fact you shouldn't want to shoot someone over property. I'm a gun owner but I don't carry a gun and I don't believe a life is worth less than property. The amount of people I know who carry a gun and have said they would shot someone for stealing is incredibly high and troubling.
I don't know if it is a direct result of the daily dehumanization of ethnic groups and criminals we are bombarded with all day long everyday or if it is much more complex but there is a real problem in the US when large groups of people don't value other people's lives.
