I assume on point 3 they wouldn’t send a civilian in because of the risk. Obviously it would have been better if they called, but I guess they wanted the element of surprise.
Well, they got that. I hope Mr. Terpstra surprises them with a lawsuit. The police ought to be a little more than trained attack dogs that you point at a target and say “sic ‘em!” Especially when anyone can say “attack.” Some yo yo in Romania could have made the call as a prank.
