I was driving along a country lane, late one rainy night after I'd been lamping a few years ago when I saw in the road ahead, some flashing hazard lights of several cars parked up in the road and some silhouettes of people moving around. I approached slowly in the car and realised that a lively bullock calf (250-300lb) was loose in the road and the people were milling about trying to stop it from escaping in the direction of a junction of a main road, some 300 hundred yds away. This stretch of lane has very high, steep sided stone hedges.
The very moment I arrived on the scene, the calf broke loose and ran through the people/cars towards the main road so I followed after him in the car and managed to overtake him (without hitting him) in the narrow lane and stopped the other side of him about 50yds short of the busy main road, put the hazard lights on, got out and opened the car boot. I had a torch, a shotgun, a rope and a roll of duck tape, so I held the torch in my mouth and reached for the......................duck tape. The calf knew he was trapped, I could see the anger in his eyes, he was sizing me up to make a break for the main road again Jonah Lomu vs.Mike Catt style, but fortunately for me, the farmer arrived from the other direction in his tractor at this point and he was angrier than the calf

so we managed to tackle the slippery devil to the ground, duck-tape his feet together for long enough to tie him properly and then rolled him into the front loader for transport back to the farm. We all ended up a bit black and blue but I never even thought about shooting him (the calf, not the farmer)
Now I realise that a calf is nothing more than an angry bull in miniature, and he didn't have proper horns but the public had already phoned the police and I really don't know what might have happened when they showed up. I have a lot of repect for our police forces but I can't imagine average pc plod and wpc plod tackling and tying a cow of any size.
I am sure that if the police had someone with a 4x4, a dart rifle and some extra heavy-duty duck tape

, they could avoid most of these unsightly public killings, which as we've seen are usually captured by the public on their camera phones. I reckon they only shoot animals with live rounds because they're not properly trained/equipped to attempt live capture. Although that said, I believe proper calibre guns should be available at all times as a last resort.
