Several states are enacting statutes, to test their durability under anticipated legal challenges from the NRA, statutes that use taxation, the level of which is calculated to reflect the monetary losses to society, from gun violence, as a way of making gun purchasers pay for the full social cost of the firearms they buy. 
Taxation and restrictions of ammunition purchases,  (avenues toward gun safety that are not  protected by the Supreme Court's recent extremist 5-4 ruling on the 2nd Amendment - The Heller Case, in which the right-wing majority of judges followed the NRA's lead, in ignoring the plain wording of the Constitution, to wit: " "A well regulated Militia, being necessary to the security of a free State. . .") may be another way to lessen the super-abundance of lethal weapons in America, where guns now far outnumber citizens.

More Americans have lost their lives to guns, just in the last 45 years since the NRA became an extremist organization, THAN WERE KILLED IN EVERY WAR IN AMERICA'S ENTIRE HISTORY, COMBINED !

CRAZY.  TRAGIC.

The kinds of reforms mentioned above, particularly if they are pursued in the name of "Gun Safety" and not the trigger words "Gun Control",  are actually supported by the moderate, sensible majority of NRA members, who simply enjoy safe gun ownership, a category of Americans that includes beloved members of my own family.
