The police seem to think that the shots are being fired from about 150 yards or so away. That isn't a hard shot for a .223 firearm (rifle or handgun). The shooter is hitting targets that are moving slowly and in a constant fashion or are stationary.
If this is the same person committing these crimes, I think he or she has made a mistake by moving south into Virginia. We can carry here.
Last thing I have to wonder about is if the shooter is using a suppressor on his firearm. The seeming confusion of where the shots are coming from would suggest this possibility.

Many of the Palistinians, including the official "Security Forces" also use the M-16. They either steal them from the Israelies, buy them from Israeli soldiers/reservists(probably not many) or on the world open market. I think we may have provided those used by the "security forces" as part of Camp David accords...gee thanks Mr. Bill..NOT!
