The problem with heavily focusing on Arabs while paying less attention to other threats is that Arab Islamist terrorists aren't the only problem aviation security needs to deal with. Focusing most of the security effort on Arabs is a good way to fight the war of 19 years ago, but it leaves the air travel system vulnerable to upstart terrorist movements that see the lack of universal security as an exploitable vulnerability. For example, there's nothing to say that America's right wing terrorist groups won't decide to switch from shootings and vehicle ramming attacks to attacks on air travel. The TSA ought to be prepared for this, or any other, emerging threat.
