How sad to see the lunatic fringe again battling the police and giving the animal rights' movement a bad name.

Although the majority protested peacefully within the law, the vocally-led yob element could always be relied upon to ignore their spokesman's earlier assertion that they "will behave in an orderly fashion".

In the circumstances, one can only applaud the decision of "the few" not to accept any treatment that has been developed using animal research programmes, with the potential to benefit much of mankind, including yobs, but which run counter to the criminal element's misguided ethos.
