The Brit criminal element is enabled and coddled by the left. Innocent men like farmer Tony Martin suffer political oppression of the worst sort for exercising basic human rights.
But does being coddled by the left make the thugs themselves leftist? I doubt it. Also it's a mistake to assume that cases like Tony Martin's are frequent. When they happen, they get so much coverage and debate because they're rare, not because they're typical (if they were, they wouldn't get reported). In reality, domestic life in most of the UK is pretty safe most of the time, though I wouldn't wish to minimise the seriousness of those cases when it isn't.
