Time to cut police budgets...
Hourly cost of manpower & 15+ police vehicles plus a 'copter?
On the other hand I read that one escapee cow jumped over the moon, they'll need a bigger budget to tackle that one.
Other responses seem split - broadly speaking those with agricultural experience think the cops were grossly over-reacting while the townies seem happy with a bigger show of force than for a mad-axeman on the loose. I'm guessing it was a nice sunny day, the cops were getting bored sat at their desks or, heaven forbid, dealing with crime and fancied an excuse to get out and wave their guns around.
