I think them only thought this man maybe just wanted be picking up. But they really make a bad decide, this man had a gun, maybe he is a crime that actually crushes the bank and avoiding the police now, he need a car to escape, so he get in this car with a gun.

I firmly believe that the things will happen is these men use other three men for hostage, and he wants to meet their teammates, and escape out this country to avoid the police. I think the hostage maybe will injury or die because they cannot avoid the crossover point. Finally, this man has been caught by police.
