No guns allowed, declares city, it's a 'snow emergency'

Hidden state laws ban firearm sales, even possession, during crises
Residents of King, N.C., were startled earlier this month when a declared snow emergency triggered a law forbidding the possession of firearms in public.
Furthermore, North Carolina isn't the only state where authorities can ban gun sales, or even possession, upon declaration of "emergency," even though what constitutes an "emergency" might be deemed questionable.
According to North Carolina statute 14-288.7, when a municipality declares a state of emergency in which "public safety authorities are unable to … afford adequate protection for lives or property" – such as during the recent East Coast record snowfall – "it is unlawful for any person to transport or possess off his own premises any dangerous weapon."

President Obama declared a National Emergency for H1N1 October 23, 2009.  It is still in effect to this date!

Notice that, according to the 1973 Senate report, under a formally declared "national emergency" -- the incumbent president now has the LEGAL POWER to: "seize property; organize and control the means of production; seize commodities; assign military forces abroad; institute martial law; seize and control all transportation and communication; regulate the operation of private enterprise; restrict travel; and, in a plethora of particular ways, control the lives of all American citizens."
