As a further threat, there have been dark whisperings of a possible ruse by Republicans to pack the Reid bill with pro-gun rights amendments that would turn the legislation on its head, transforming the bill from a measure to tighten gun regulations post-Newtown into a panacea for a gun-owning free-for-all. One such provision being mooted would require all 50 states to recognise concealed carry permits from other states – New York, for instance, would be forced to allow a man with a permit from Arizona to carry a hidden gun in its bars.
"That's an old favourite legislative strategy – to add poison pills to a bill that would make it difficult to support and that way kill it," Vernick said.
