Not only did Samaha buy 10 guns in one hour with incredible ease and no questions, he could have turned around and sold those same guns right in the parking lot. In fact, while standing next to his trunk full of guns, Omar was approached by a man who thought he was a seller. Omar knew the gun show loophole existed, but he was still shocked by how easy it was for him to buy guns with no questions asked.
"Anybody can do it," Samaha said. "And it's for real. It's that easy. Anyone. Someone who's adjudicated mentally ill, someone who's a known felon. Someone who has a history of crime. I think people don't realize how easy it really is."
In fact, the Bureau of Alcohol, Tobacco and Firearms (ATF) reports in their investigations that private sellers at gun shows are a major source of gun crime in the country. In the two years since Reema's death, Samaha has fought hard to get the loophole closed in his home state of Virginia.
He has lobbied lawmakers, spoken publicly about his sister and even launched an online campaign about the dangers of guns on campus. A law to close the gun show loophole has come up twice in the Virginia State legislature, and twice the body has voted against the bill, even though it was one of the key recommendations to come out of Kaine's Virginia Tech Review Panel.
When Virginia lawmakers voted against closing the loophole, Samaha was shocked. "It really made me wonder what kind of people we have making our laws," he said.
Among those who voted twice against closing the gun show loophole is state John S. Edwards, a Virginia Democrat who represents the district that includes Virginia Tech. After repeated attempts to reach Edwards, the state senator did not respond to calls from ABC News.
Gun rights groups don't want to see the loophole closed because they fear that background checks will hurt business at gun shows, and also threaten privacy rights. They also argue that the Virginia Tech shooter didn't buy his gun at a gun show. Seung Hui Cho bought his gun legally at a gun store even though he had a documented history of mental illness. That breakdown in the system was addressed immediately following Virginia Tech, but families of the victims argue that with the gun show loophole still open, it is just too easy to buy a gun with no questions asked.
For Samaha, it's not about the right to own a gun, it's about how easy it is for guns to end up in the wrong hands.
"We're not trying to keep guns out of the hands of good citizens. If you can pass a background check, which anyone can do in a matter of minutes, then you can buy guns," he said.
Former ATF agent Gerald Nunziato was with Samaha at the gun show in Richmond, Va. With years of experience fighting gangs and drug organizations, Nunziato was all too familiar with the guns that Samaha bought.
"My experience as an agent in Detroit and Miami is that these guns [shotguns] would be sawed off at the barrel," he said. "They're a very high-powered scatter gun that's used a lot by drug gang members 'cause they're easy to get in and out of your car."
Even though Samaha immediately turned in all the weapons he bought at the gun show to the Richmond Police Department, Nunziato pointed out that if Samaha had wanted to, he could have caused a lot of damage with the guns he purchased.
