The other story here is that the NRA has managed to make enemies on both sides of the debate, by issuing an alert last week urging Missouri residents to contact their state senators asking them to oppose the bill. In that alert, the group made some assertions about the theft reporting requirement that appear to have been made up from whole cloth.
As for why the NRA might oppose such legislation, perhaps it's simple tactical concerns--perhaps they don't see such laws ever surviving the inevitable federal court fight, and thus don't want the gun rights movement burning political capital for nothing--the "Vulcan chess masters" explanation. Somewhat similar thinking was apparently at the heart of their original obstruction of what eventually became the District of Columbia v. Heller case. On the other hand, perhaps they see more moneymaking potential in fighting the gun rights war, than in winning it.For now, though, if the NRA was hoping to kill SB 613, they are just as disappointed as the anti-gun, federal government über alles nanny-statists.
"Perhaps they see more moneymaking potential in fighting the gun rights war, than in winning it." EXACTLY.
