is the clock ticking (again)?

Awhile back, we asked Is the clock ticking? that is, toward another attack on the US. We heard a recent statistic that every time bin laden releases a _video_ tape, there is a major attack or more than one, within 53 days. We've been trying to verify this, but the log provided int he post above is the best we could do. Questions have arisen in several quarters recently about the personal physical security of bin Laden given that he is able to issue to many messages . . . Just pointing these things out . . . perhaps the US can't pressure the ISI too hard for some reason . . . interesting . . . UPDATE: Forgot to mention that on the strength of the bin Laden -video and attack link, the FBI arrested some 700-800 Muslims the weekend before the US election -- many for relatively minor reasons, like immigration violations. These were people it had already been keeping an eye on for some time, hoping to glean intelligence by watching them. They then interrogated all and found no reason to keep them. Heard this secondhand from a friend in a position to know. Checking stories from the Monday before the election, November 1st, might show some corroboration.
