Should there be Tougher Gun Control?

I believe that gun control laws should be in forced. For instance, think of the Columbine high school massacre of 1999 where approximately 12 people died. The authors of this massacre were two students of seventeen and eighteen years old. The question that comes to my mind is that: how two minors could have access to those powerful weapons, with which they killed and harmed so many people? Is it due to the easy access to gun that the United States has? If there where tougher gun control laws maybe those adolescents wouldn’t have access to any guns and the accident could have been prevented, so I defenetly believe that gun control laws should be in forced.
