all or -- >> i haven't talked -- nobody is contacting me. i called fbi first line. fbi line. if you have any hints, let us know. that's the number i called because knowing these two boys, knowing -- believing, strongly believing they wouldn't do this, that's why i called. but i called not right away. first reaction was anger. how could this happen? how could this do this? for what? for the sake of what? what belief? what prompted them to this? this reaction. but then i went through material, whatever is in there. quickly, quickly. my first call to fbi, they could not have done this. where evidence? all you're showing, that's just footage. two guys are walking. and i found it strange, tamerlan is walking in the front, dzhokhar is in the back. why wouldn't they come together?
