A campaign by gun rights advocates to make it easier to use deadly force in self-defense is rapidly winning support across the country, as state after state makes it legal for people who feel their lives are in danger to shoot down an attacker - whether in a car-jacking or just on the street.
The law has spurred debate about whether it protects against lawlessness or spurs more crime. Supporters say it's an unambiguous answer to random violence, while critics - including police chiefs and prosecutors - warn that criminals are more likely to benefit than innocent victims.

Besides Oklahoma, the nine other states to sign on are Arizona, Alabama, Georgia, Idaho, Indiana, Kansas, Kentucky, Mississippi and South Dakota, according to the NRA.
I didn't see Paul Helmke quoted, but as the new head of the Brady gun-control people, he will surely be drawn into it. The idea that I don't have to retreat before I respond to a threat with force seems fairly commonsensical to me; it's at the heart of our right of self-defense. Whether these laws lead to rampant vigilatism, hordes of people shooting first and asking later, remains to be seen. It doesn't seem to have worked out that way in Florida.
