[on reports that police were looking for a "darker-skinned male" in connection with the Boston bombing]

Aha! That’s why the perps didn’t detonate the bombs at the front of the pack, as that is where all the Kenyans and sub-Saharan folks were (you know, the folks that are about 6’6” and weigh about 120 pounds and can run all day without breaking a sweat). They waited until the slower and pokier white folks came trotting toward the finish line before detonating the bombs. I smell racism!
