One year after the Virginia Tech massacre, two student groups are debating two very different approaches to stopping gun violence on colleges and universities.One group calls for more laws and less guns. The other believes guns can keep students safe.Supporters of ProtestEasyGuns.com held a lie-in at the state Capitol Wednesday.The protesters were silent for three minutes to demonstrate what they believe is the typical amount of time it takes to buy a gun in the U.S."I felt it when I laid down. It was being part of something that we want a change. We want to make a change. This is getting out of control," Jameela Khadiwala said.The group believes stricter gun laws that, in part, extend the waiting period to buy a firearm would reduce access to dangerous weapons."It's just way too easy. With the responsibility of bringing a child into this world your mind changes. You go, hey this is not acceptable," said Armen Khadiwala, Jameela's husband.At the University of Colorado in Boulder, Jim Manley said students with concealed weapons could help in the event of a Virginia Tech, active shooter situation."People who are dedicated to committing an awful crime don't care how long it takes them. They're dedicated to carrying out their task, and it falls on their victims to try to fight back," Manley said.He's the campus leader for a nationwide movement that resulted from Virginia Tech called Students for Concealed Carry on Campus.Formed in November of last year, Manley cites 100 Boulder supporters now."It's grown really rapidly since then. I'm really surprised at the support," Manley said.On Tuesday, April 22, Manley and supporters will try to gather signatures asking the University of Colorado's Board of Regents to reverse their campus weapons ban and allow permitted, trained gun owners to bring concealed weapons to class."The shooters at Virginia Tech and Northern Illinois University followed all the gun control laws. What will help students is to be able to fight back. To have that choice. To not have to cower in the corner," Manley said."You're going to have people stepping up, trying to save the world. I just think that's going to cause more of a problem. I mean, more guns, I don't think that's the solution," Mr. Khadiwala said.A school spokesman said campus police are best for handling an active shooter situation based on extensive, intense training.A spokesman for Colorado State University in Fort Collins told 7NEWS that school allows concealed weapons permit holders to bring firearms to class, but not into residence halls or dormitories.
