Are Knives next?

We had the knife attack (or a box cutter) on a college campus in Houston Texas.  The NKA (National Knife Association) has not commented as of this writing but I am sure there will be a move by some politicians to have background checks and fingerprinting on all people trying to purchase a knife.  And rest assured, you will have to be 18 years of age of older to purchase a knife.  And God forbid if you took any type of medication the government may deem not compatible with possession of any type of weapon, it will be removed by armed government officials.
