"Previously Unknown Group?"

We're constantly hearing about depredations in the Middle East by "a previously unknown group." But are they REALLY "unknown? It's a common "modus operandi" among radical Islamic terrorists to "create" new groups by simply starting to operate under a new name, using the SAME people. This tends to confuse the liberal news media, which wants to advance the terrorist cause. Since they WANT to confuse America, they like it. (Just common sense)
