Why did the federal police come to arrest Quaid suddenly? They should not have arrested him because everything was going according to their plan. First I thought, the man in the Recall might have pressed any alarm, but that does not fit well as they tried to kill each other(the man of the Rekall and the police). So why and how did the police come to arrest Quaid?
Also why did the police kill the man and why was the man was shooting at them, too?
