When the police stopped that car and saw blood on the ground, why did...
... they not act upon it, even subtly perhaps?
Seriously, remember that scene when the police stopped the car with the gang who had the body of the dead man in their trunk, and they were explaining how they were government officials and whatnot, when that cop saw drops of blood on the ground right where the car was, why did he and the other officers not act on it?
Like OK, maybe telling them that directly would've made them pull out their guns and shoot them, but if they were acting subtly on it, like getting their registration number and quietly alerting other officers of it somehow - I mean - that was the right thing to do, yes?
Or did that cop and other cops not notice the drops of blood on the ground next to the car?
The greatest trick the Devil has ever pulled was convincing the world he didn't exist!
