Eco-warriors or vandals?

The Mail reports that:

"Environmental activists have carried out a spate of attacks on 4x4s under cover of darkness.

Tyres have been let down or slashed, with notes left on motorists' windscreens accusing them of contributing to climate change.

More than 100 so-called Chelsea Tractors have been targeted in recent weeks in wellheeled suburbs of South Manchester. "

Eco-warriors or just plain vandals? You decide...
