Airline's Becoming Less Safe?

A policy change to air travel was supposed to be put into affect this week, as passengers were to be able to carry pocket knives onto planes. However, this policy has been delayed for an unknown time due to a reconsideration. Click here to read more on this controversy.

TSA argues that by allowing pocket knives onto planes, they could scan for more threatening weapons with more ease. Although a valid point, I do not think that should be the reason why we start allowing a weapon to be carried onto airplanes. Pocket knives can pose a threat to many lives on an airplane depending on the situation. It seems ridiculous to sacrifice our safety so that we can get through security lines quicker. The system that has been in place with TSA has been successful since 9/11, so I don't see a reason to change it now. What do you think? Should this policy pass?
