I also now just saw an interview with a FL congressman (didn't catch his name) introducing, or I guess reintroducing, legislation to keep anyone on the terror watch list from buying or owning firearms. The secret terror watch list that is.
One of his arguments was that assault weapons and hand grenades (yes, he actually said that) shouldn't be available to people on a watch list, and that 80% of NRA members approve of that message.
