plot hole *minor spoiler*
After Travolta becomes sure of the fact that the tire was shot, some ninja enters what I believe is a police station - to replace the shot tire with a new one.
Can it be actually possible not to notice the shot tire when the car is taken from the river, examined, taken to the station?? High-profile official is dead, he could have been the next president by the words of some minor character... WTF?
