Family members watch as 11-year-old Mark takes aim with an AR-15 style assault rifle on the exhibit floor of the George R. Brown Convention Center, the site for the National Rifle Association (NRA)’s annual meeting in Houston, Texas on May 3, 2013. Tens of thousands of National Rifle Association members gather in Houston this weekend for the first time since the U.S. Senate rejected a plan last month to expand background checks for gun buyers, but officials say attendees will not sit back to celebrate victory. The family did not want to disclose their full name due to security concerns. REUTERS/Adrees Latif (UNITED STATES – Tags: SOCIETY POLITICS TPX IMAGES OF THE DAY) – RTXZ96A
