You know cows kill a fair few folks in the UK right.
The summery said it was reported running at members of the public.
While I am sure there are better ways to deal with it. As lets face it the car is only going to scare it more. Scared out of control cow are freaking dangerous.
There have been a number of news articles talking about killer cows over the last few years. Even though it is rare. Average of a few a year and normally when the cows are stressed for some reason. But let's face. Media is not known for responsible reporting.
But a cow in the middle of a busy road acting aggressive towards humans. Is a genuine threat. I can def see a cop being to scared to approach it without the car and thinking removing the cow is urgent.
Of course the action is dumb. Clearing the road and calling a vet would be better. But I can fathom a cop panicking.
