These authorities are about 24 hours late to the party. People on the internet and here at FR all had these two guys pegged about 20 minutes after the first photos were circulated yesterday morning.
The authorities were apparently all looking for angry white men. We were all looking for younger Arabs. These guys stood out like a sore thumb. We were right. They wasted a good 24 hours because they wanted to be politically correct.
They probably flew back to Yemen sometime yesterday while Obama was melting down over his failure to exploit the Sandy Hook massacre.
Political Correctness kills.
Goes to show that the authorities are playing catch-up.
