Disturbing catch at Hot Air.

The father of suspected Boston Marathon bomber called on his son today to give up peacefully, but warned the U.S. that if his son is killed “all hell will break loose.”

Anzor Tsarnaev spoke to ABC News from his home in the Russian city of Makhachkala as Boston police carried out an intense dragnet for his son Dzhokhar Tsarnaev. ….
The elder Tsarnaev insisted that his sons were innocent, but said he would appeal to his son to “surrender peacefully”

“Give up. Give up. You have a bright future ahead of you. Come home to Russia,” the dad said.

The father warned, however, “If they killed him, then all hell would break loose.”

Hell has been breaking loose this entire week, pal. It won’t stop with the probable demise of the younger brother, now that we’re learning that the pair appear to be Islamic terrorists who trained for violence overseas, exploited our immigration system and were registered voters in Massachusetts despite not being US citizens.

All of that said, it would be most useful if he is taken alive. We need to learn where he got his weapons, the grenades he is reported to have, where he learned how to build bombs, possible links to groups here in the US or overseas — everything.
