Extending the ban on plastic firearms

Alan Fram has a Time article about plastic gubs:

A Senate vote to renew an expiring ban on plastic firearms capable of evading metal detectors and X-ray machines is shaping up as a bittersweet moment for gun control supporters, days before the anniversary of the deadly mass shooting at Sandy Hook Elementary School.
The vote to extend the prohibition on plastic guns for another decade responds to a growing threat from steadily improving 3-D printers that can produce such weapons. But gun control advocates seem sure to lose an effort to impose additional, tougher restrictions on plastic firearms— a harsh reminder of their failure to enact any new Federal gun curbs in the year since twenty first-graders and six educators were murdered in Newtown, Connecticut.
The slayings on 14 December 2012 prompted the newly re-elected President Barack Obama to push gun control to the top of his domestic agenda. But Congress approved nothing, and gun control advocates face the same uphill struggle in 2014, complicated by internal divisions over what their next step should be.
“The gun lobby still has enormous power in Washington— more, frankly, than I thought they still had,” said Senator Chris Murphy, a Democrat from Connecticut, who represented Newtown last year while in the House.
Illustrating the roadblocks that have thwarted gun control forces, an effort by Senator Chuck Schumer, a Democrat from New York, to make plastic guns more detectable by requiring them to have a permanent metal part seems certain to fail. His plan is opposed by both Republicans and the National Rifle Association.
The Senate is then expected to easily approve a ten-year extension of the ban, which would otherwise expire Tuesday.
Schumer and other Democrats, as well as gun-control advocates and law enforcement officials, say there’s a problem with current law on plastic guns: it lets gun makers meet its requirements by including a metal part that can be easily detached— thus letting the weapon evade screening devices.

Rico says they should give it up; the gun nuts are always gonna outwit the control freaks...
