"'Sleeper' cells belonging to militant Lebanese Shiite group Hezbollah are present in Western Europe, Latin America and in southeast Asia and been ordered to be ready to carry out terrorist attacks should Israel prolong its military offensive against Lebanon, according to unnamed German intelligence sources."
I'm not saying this guy was Hezbollah; I am saying the MSM may want to reserve judgment until we know one way or the other what he was. As Hewitt puts it
Any crime of violence done to avenge a political grievance is an act of terrorism. Haq's murder of at least one employee of the Jewish Federation is an act of terrorism. What the public needs to know is the likelihood of other such acts being committed by similarly situated individuals.
