It was the same shop that sold the killer gun to Hasan. Had it been a different one, I doubt we would have gotten a heads up.

Reports we heard here in Austin was that the clerk's interest was piqued by the guy asking naive questions about what was "smokeless" gunpowder - and then commencing to buy several pounds of the stuff!
Chances are any gun store folks would find that strange and report it.
