I'm no ballistics expert, but I have to question whether a laser etched serial number would remain intact after a bullet is fired through the air and into something.
As far as the NRA, the NRA typically opposes these things because of privacy concerns. I'm a life member, but I sometimes think they take those privacy concerns too far, just as the ACLU does for every other effin' topic. Unless they can demonstrate the laser number would be easy to fake or otherwise could create false criminal liability for the owner of the bullet, I'm not in agreement with them on that issue.
As far as the Florida "self defense" law, based on the article it appears that the state simply codified into statute the existing, and long standing, rule of self-defense, to wit, that a person who has a reasonable fear of imminent death or serious physical injury has a right to use deadly force in self defense. That's nothing new.
