Two British men are facing prison time for what prosecutors called the "arboreal equivalent of mindless thuggery." Daniel Graham, 39, and Adam Carruthers, 32, were found guilty Friday of cutting down the famous Sycamore Gap tree in Northumberland, England, the BBC reports. They were remanded into custody ahead of sentencing on July 15, with the judge warning that they could face "lengthy" sentences. They were convicted of two counts of criminal damage for the felling of the iconic tree and damage to the nearby Roman landmark Hadrian's Wall.
