In Today's Politico, two reporters, Josh Gerstein and Jennifer Epstein ponder what the Boston bombers' motives could have been:
Djohar Tsarnaev's webpage reportedly described his "worldview" as "Islam." It is reported that Tamerlan Tsarnaev's youtube account focused on Islam and had a playlist called "terrorists." Both (reportedly) tried to kill and maim as many random infidels as they could.
Politico claims its confusion comes from not understanding why Chechen emigres would kill infidels in America rather than Russia — as if Islamists would consider that to be an important distinction.
It is more than a decade since 9-11. Politico cannot be this ignorant unless it is trying to be.
