He mentioned tracing ammo last week also with regards to Mexico, not sure which speech...frankly i can't tell one speech from the next anymore. Either the one before the last one or it might have been the one before that one. Maybe someone else knows if it was during Mexico speech 1 thru 3 or 4 thru 6 ago? Is that a new tactic, Keep talking until everyone stops listening
Anyway...the ability to trace ammo was mentioned, but maybe reading bar codes off the boxes was the intention.
Edit: found it. Closing loopholes
, ballistics and ammo info are something Mr Holder will be working on.
