NRA tweets glamour shot of AR-15 while students hold National School Walkout protesting gun violence

The NRA had a pretty tactless response to the National School Walkout on Wednesday. 

March 14 marks one month since the tragic mass shooting in Parkland, Fla. that left 17 people dead, and students nationwide are walking out of classes to honor those who died and protest gun violence.  

On a day being used to remember children killed by an AR-15, the National Rifle Association, a pro-gun lobbying group, tweeted a photo of an AR-15 with the caption, "I'll control my own guns, thank you."
