so now it's a manhunt. >> michael, it's was this person working alone? was this a small network? how far could this person have gotten? what questions are you asking? >> yeah, those and, i mean, look, if it was the driver working for this polish truck company, this is a guy who then crossed the boarder from a foreign country into berlin, premeditated clearly and got killed in the process of committing this act of mass murder. if it's not then as i said yesterday there's a level of operational security and sophistication here because that means there's an unknown assailant running around who took the decision not only am i going to wage a mass murder but i'm going to hijack a truck, not just any truck but a truck with 25 tons of steel in it so it's a batteri ining ram of a vehicle. he will have had to had surveil the truck and found a way to take it over and plow into a bunch of people. that doesn't seem to me like some random crazy
