I would have closed the road
How, at 3- 6 a.m. and given all the difficulties identified above re lack of available officers and cars, the need to shut slip roads overnight, and the weight of speeding traffic at that time? And how would closing the road guarantee that the dog wouldn't just run back onto the area that wasn't closed?
called in the dog unit or whatever regulations the police usually have to follow to catch an animal in the road.
They're not available at night time.
What exactly do you want me to say as a non-trained officer?
You're the one who keeps saying they could have done something else. You need to be able to say what that was.
I don't have the answer, but I'm allowed to believe dangerously driving and hitting an animal is the right way of dealing with it either.
Sure, you're allowed to believe that elephants fly if you want.
Others may think that's a stupid opinion, but as I said, just my opinion and I stand by it.
Fine, but you don't get opinions out of nothing: you need some facts to back them up if you want people to take them at all seriously.
