The details are disturbing. There are 310,000,000 guns in the U.S., one for every person. No country matches this level of deadly force potential. The closest contender is Yemen with 11 guns for every 20 people. In 2011, the NRA spent over 231 million to make sure we remain #1 in guns. At least, for a brief moment in 2014, the NRA had a brief fit of honesty and found the open carry gun guys and gals in Texas trying to get into restaurants and taunting an unarmed veteran, all while filming themselves, to be weird. They backpedaled quickly as they started losing a few of their most strident members ... sadly.
I suggest you avoid the comments, however. Ugh.
Also check out the Washington Post article, "Depressing Number of the Day: 74 School Shootings Since Newtown:" http://www.washingtonpost.com/news/post-nation/wp/2014/06/10/depressing-number-of-the-day-74-school-shootings-since-newtown/
This madness has to end.
