I just found this in my draft folder from a while back. It's kind of old news, but I think it's still worth mentioning.
Gun control advocates failed to gain local government and law enforcement agencies' access to gun sales data.
The House Appropriations Committee defeated two attempts by gun control advocates to strip four-year-old restrictions on the use of information from Bureau of Alcohol, Tobacco, Firearms and Explosives tracing gun sales. The votes were a victory for the National Rifle Association and came despite the Democratic takeover of Congress in January.
One side argues that gun sales data will help law enforcement agencies track gun dealers who sell guns illegally. The other side argues that there's privacy at stake, and there's a chance that police officers' identities could be inferred. A big victory for gun rights advocates, or so the the article might suggest.
My opinion -- even if gun sales data were given to law enforcement, how could anyone guarantee data integrity? I think it's fair to say that dealers selling guns illegally aren't going to provide accurate reports. Sell a gun under the table with cash, don't report it, and the data doesn't reveal much. Am I missing something here?
