(CNN) -- One was a "nice guy," who was "friendly and very polite" and "just wanted to help everybody." Then there was the "crazed ... animal" -- someone who'd brutally hack to death a man in broad daylight on the streets of London, then tried to justify it and suggested there was more violence to come. Two vastly descriptions, for one person: Michael Adebolajo. While British police have not named any of the men arrested in connection with Wednesday's gory slaying of British soldier Lee Rigby, one of them didn't hide his identity at the time. That man -- toting a meat cleaver and large kitchen knife in his bloody hands -- sought out a cell phone camera minutes after the attack to justify what he and another man allegedly had just done.

The former associate -- who was himself "born again" into @placeholder, but has since shed his radical views -- said that "like all of us, (Adebolajo) had a literal understanding of Islam."
