I registered on their little site and left this response for this starry eyed 2nd year Political Science major.
First, terrorists generally use bombs, not guns.
Second, do you really want to give the government the authority to suspend any of your civil rights at their sole discretion, without due process?
It doesn’t seem you’ve thought this matter through. Remember, the power you give the government today to control someone else, can be used tomorrow to control you.
If you insist upon worrying about guns in the hands of terrorists, worry about them bringing in machine guns from South America, not what they might by off the shelf in the U.S.
