I’ve been meaning to include this for years, but finally found the phrasing I wanted from Instapundit (who I think came up with this).
Reminder: The justice system isn’t really there to protect citizens from criminals. It’s there to protect criminals from citizens. And within limits that’s a good thing, but when you create a state of nature, you get a state of nature. And in the state of nature people absolutely do kill to protect their property from marauders.
See link for context.
