The answer, of course is "no". How about confirming with the "witness" what she saw and approach the vehicle cautiously, pull the driver out, explain the reason for the stop and question him regarding the cash.
As for the dog, the police should absolutely allowed the car doors to be closed. They were wrong and should be held fully accountable for their inaction but, I heard the owner on the radio refer to the dog as a "bulldog" and later got the impression from callers and the show host that it was a English Bulldog, now they just called him a "mixed breed bulldog" and now the police are calling him a "pitbull". Could be the cops trying to justify the senseless murder of a families pet, but I'd like to see a photo of the dog (preferably a "before" picture). If he turns out to have been a pitbull, the police were negligent in not closing the doors but now there is a very real possibility that the "family pet" was now in attack mode. Sorry, but I don't have any love or respect for Pitbulls or their owners. Flame away...
Sure thing. Next they'll be telling us the dog was on PCP.
