There's a talk radio host here in Denver, Michael Brown (of "Brownie, you're doing a heck of a job." fame - former FEMA Chief under George W during Katrina) - that calls it the "Taxpayer Relief Shot" since, if the home intruder dies, then it's a lot less cost to the taxpayer compared to trials and, god-willing, incarceration (not a given in today's political climate).
