In my opinion, no. The new regulations are, according to the Hill:
1) will grant tribal police access to NICS;
2) authorize law enforcement agencies to use the system to run full background checks before returning guns that have been seized or confiscated during the course of investigations;
3) involves consolidated, electronic storage of information on gun purchases that have been denied via the NICS system.
While I can see potential for abuse, especially considering this WH and the Holder DOJ, 1 and 2 seem like common sense.
And yes, I’m a gun owner and NRA member. But I still don’t see what this has to do with Sandy Hook, which none of these regulations would have remotely prevented.
Dangit, ya beat me...
