Because burglaries gone bad where the residents get murdered never happen?

It's not about your stuff versus the burglar. It's about your life (and potentially the life of your family if they are there) versus the burglar's life. No one shoots a burglar over stuff. Once they are caught, they're clearly not going to be stealing anything more unless they murder the residents who caught them. That is the worry.

None of these concepts are that complicated to understand. It's bizarre that they don't seem to be able to understand them. Leftism is a mental disorder.
