Airpory Security-Needed Elsewhere?

Compare this: Blowing up a jet airliner with 200 people onboard or blowing up a mall with 400 people shopping. The truth is, there is a much higher chance of someone bombing a store than an airliner. Why airport security? We need security checkpoints (like x-ray machines and metal detectors) at malls, stores, parks, and other public places. Also, it is SO much easier to sneak a bomb into a store and blow it up than to sneak a bomb on an airliner. The TSA (Transportation Security Administration) should be called the MSA (Mall Security Administration) or some other name than TSA because of the problems that happen down on terra firma, not at 30000 feet. More people get killed at stores than on airliners. I hear of store shootings all the time and maybe a airport security breach like once every few months or even years. We really need to start looking into having security checkpoints at stores and public places and not airports. Just think about the idea. Anyone agree with me?
