福克斯新闻 Threat Of Plastic Guns塑料枪的危险（在线收听）

The law that bans undetectable firearms is set to expire, sparking concern about plastic guns.

FOX News Radio’s Steve Taylor reports from Washington:

There are guns that metal detectors can’t see because they’re made entirely of plastic. The gun parts can be created on a high-tech, three-dimensional printing device. These weapons are not legal to carry or use under federal law, but that law expires next month. Attorney General Eric Holder says this is a serious threat to law enforcement and to anyone who flies. Holder asks Congress to renew the law. However, that would require bipartisan support and quick action, two things that Congress hasn’t done well in recent years.
