The president is on his way to South Africa for Nelson Mandela’s memorial service, so the Undetectable Firearms Act will be signed by Autopen tonight, extending the ban on plastic guns for another 10 years.

The Washington Times’ Emily Miller, author of “Emily Gets Her Gun,” is not impressed.

Will citizens sleep more soundly tonight knowing they’re safe for another 10 years from plastic guns that don’t exist?

By Knoller’s count, this is the fourth time the president has used the Autopen to sign legislation.
