I have it on reasonably good authority that there was a spate of antisocial behaviour in the area that evening and that the vehicle that was set alight at his gates was not the only vehicle set alight/ serious criminal damage caused in the vicinity that night.
Perhaps he was deliberately targeted by a group of yobs out causing general destruction and thought they would have a pop at him too or perhaps he was just unlucky to get caught up in it.
For what it's worth the badger issue is much bigger than just bTB. If we allow predator numbers to go uncontrolled then it seriously harms wildlife in the area, once the prey animals have been reduced in number predators come after livestock. Farmers are fed up with being blamed for 'destroying the countryside' when for the last 20 years many farmers have been trying un-ruin it from a wildlife perspective and are having their efforts completely hampered by predators on the ground and in the sky.
Lapwings, curlews, hedgehogs, dormouse, voles etc have no chance of the countryside is overrun with fox, badger, mink, buzzards, sparrowhawks, gulls etc all look I'm for an easy meal.
It's frustrating when people like Packham come at the issue without really recognising the impact of their actions on the wider ecosystem.
