Re: Lots of stupid in this thread
1... does it matter if the farmer (or perhaps a vet) owned the animal, I am quite sure they could have dealt with it until the real owner was found
2.... yeah, same applies to a broken down car, children crossing, people on pushbikes, trees... I suppose it would stop the population crisis in the world if we shot everyone who might possibly cause a problem...oh yes, forgot the police are trying this
3... Yes bullets do go through things but if you are shooting from a height it would go through the cow and into the earth (well, possibly, most likely it would deform on impact with the bone mass of the skull and stay somewhere in the dead cows head). If you shoot parallel to the ground then there really is a chance of it going through and hitting an innocent bystander... however I doubt there were a massive number of school children in the field watching the police shoot the cow... the police don't normally like an audience for this sort of behaviour.
4... The fact that the bolt is poor as a method of killing is another (important I admit) subject and doesn't mean we want the police wandering around farms all over the country randomly shooting any animal they find in order to save it distress in the slaughter house.
5... Amazingly I see SINGLE farmers herding large collections of cows (herds :) ) every day... Part of the reason this is successful is they don't use nooses and try hanging on to several tons of running cow. But maybe this is because while farmers have an extraordinary collection of blindspots and blame badgers, foxes and other wildlife for every ill imaginable they actually do know how to handle a cow.
Personally I like thinking before kicking off, although I admit things like facts are also useful before a really good rant can hit home :)
