Aw, don't be so hard on yourself.
How likely is it that a woman would lieand call the police to claim a car doing the speed limit was traveling 110mph, vs. how likely she was telling the truth about the car speeding? Her other claim that money was coming from the car was validated by the driver's admission that he left his wallet on top of the car. So it is hardly foolish to believe her when she stated that the car was speeding.
Sorry if inconvenient factors get in the way of pious bitching and damning. Like most tragic incidents, the blame is not as clearcut as zealots would like to believe.
No problem here pal. I'll just call you in to 911 next time you're on the streets with your family on vacation. I'll just make up something real good. Then we'll see what happens to you and your family. How's that sound?
I suggest you do a test and see if a wallet can remain on the car even at 50 MPH.
I bet not.
More than likely this was an nosy old bitty, who can't drive herself.
