bottom line is, they're just different strains of the same pestilence ...
Yes, there was that supposed ("supposed" because they never caught him) Pali sniper that killed 6 or 7 Israelis a few months ago and disappeared. This sniper (assuming only one with an accomplice) kills with one shot and knows how to seemingly disappear. Very well training and cunning. You could almost say that this isn't a rookie on a first-time killing spree because there have been no slip-ups (unless less you count the two survivors). And the language on the Tarot card is distinctly different from common American usage.
Chief Moose has released composite sketches of the white truck based on several eye-witnesses. But he won't release any composite drawings so far, of even the driver although the cop at the last shooting was said to have seen two people in the truck and a by-stander had a view of one of them. Early reports cited two men. But to date we've been told something about "Hispanic" appearing men after the D.C. killing and no other description. Moose doesn't want to "muddy the waters" and "get people searching after the wrong people". After the OKC bombings, the FBI had drawings of John Doe 1 and John Doe 2 out in less than 24 hours. Is it that the eye witnesses are vague on what they so quickly saw? Or what? Even a very partial description, such as saying that the men sighted weren't black, white, whatever, would begin to narrow the search, right?
There's a Hamas group right in DC and another in Springfield VA, among a total of 7 terror groups right around DC that are shown on this map. (Not to mention 2 AQ, 2 Hezbollah, and an Islamic Jihad.)
Plenty of likely suspects to choose from...
