The NICS system crashed last week after overwhelming numbers of requests swamped it. The NICS system, run by the FBI, is the database used to make sure that you're not a felon and are otherwise legally allowed to purchase a firearm (despite common misperception, not "anyone" can buy a firearm).
Hmmmm. Before the election, the received wisdom was that people were stocking up "because they were afraid that Pres. Obama would win." Now he has won.
It's almost like The People are still afraid of something or the other.
