Apparently the father believes his sons were set up and vows all hell will break lose if his son is killed by police:
ABC NEWS – The father said he spoke to his sons by phone earlier this week. “We talked about the bombing. I was worried about then,” Anzor Tsarnaev said.
He said his sons reassured him, saying, “Everything is good, Daddy. Everything is very good.”
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.”
“If they kill my second child, I will know that it is an inside job, a hit job. The police are to blame,” the father told ABC News. “Someone, some organization is out to get them.”
