The concept of "no net loss" should be implemented to keep from losing more of our Second Amendment rights.
An interesting concept for use as a political ploy, perhaps. However, the history of gun control has been compromise, after compromise, after compromise. We give up some of our rights, in return for promises of greater safety which never materialize. Then something else happens, and there are calls for yet more compromise. The citizen always loses in these compromises, and the gun grabbers and statists always gains.
