No knives and other objects that are potential threats allowed on planes.

Knives and the other articles mentioned in the petition should not be allowed on planes. They are a threat to the safety and security of the people. It is common sense to not allow these things on board. Looking for bomb threats are not the only thing that should be a priority at the airport. Safety is first for everyone. Assuring safety is and should be a priority. Not allowing knives and other things can and will safe lives. You have to consider that some people are crazy and will do anything. If anything, we should prevent another national tragedy from occurring. Allowing knives on planes is the wrong thing to do. Its common sense. I shake my head to those that ever proposed to allow it in the first place - shame.
