Wow
Holy crap is right!
Damn! That cameraman walked TOWARDS the explosion. WTF?
(1) It is amazing to see the number of people moving toward the site of the explosion to help.
(2) The immediate organization of the National Guard and Police in clearing obstacles and providing aid is heartening. These are good people.
