From the comments to my post below "Is This Relevant?" about whether the MIT shooting is related to the Boston marathon bombing (quick answer: yes):

I'm writing from within yards of where the shootout in Watertown happened. I was just getting to sleep when I heard hundreds of rounds fired in bursts, single shot, staccato, at least three different calibres from the sounds and also what sounded like grenades or IEDs (maybe pipebombs). I will say that Watertown is home to many Muslim immigrants, most of whom are great neighbors and fine people. But I've heard teenage punks sound off late at night in trhe local 24 hour store about Jihad, I suspect mostly to epater le kafir. But I'm now leaning to the conclusion that a couple of these punks may have become over-intoxicated by their own rhetoric and caused all the havoc of the past five days. I agree with other posters that the MSM and feds have done everything in their power to pin this on a couple of white, right-wing loons yet to be found (white Islamics, white Hispanics, WTF). But to my eye the suspects' pictures look a lot like many of my muslim neighbors from various parts of the Balkans, Levant, and Middle East. Color me prescient if I'm right. Call me a hateful right-wing, racist loon if I'm wrong.

Thanks. Keep your head down. One suspect is dead, but the cops are now searching door to door in Watertown for the other suspect (or suspects).

[Update: Suspect No. 2, the guy on the white hat, is the one on the loose. The cops think he set off motion detectors in a building in Watertown.]

In case this surmise turns out to be right, here's my 2010 review of Chris Morris's British comedy Four Lions about a terrorist attack on the “unbelieving Kafir slags" taking part in a marathon.

But, we shall see ...
