Waving placards,demonstrating en masse and venting vacuous platitudes on any matter is of course de facto guaranteed by our unwritten constitution.Largely because any given demonstration by itself doesn't herald much if any of a change in government policy or challenge any set of accepted legal norms.
Unless,that is we have a government in meltdown and we're in the midst of an unprecedented fully blown crisis of constitutional legitimacy.Which we are.
Up pop a mysteriously funded,fully formed campaigning organisation capable of launching a planned,co-ordinated two weeks long disruption of daily London life and traffic flows. An eco-millenarian cult that has metastasized across the european continent and has its own High Priestess/Delphic Oracle in Greta Thunberg.
In the face of this largely gentrified,professional middle class mob espousing veganism,population eugenics and gluing themselves to train carriages and Ministry entrance doors,the Metropolitan Police in collusion with the Home Office nakedly surrendered and were manifestly brazen about their cowardly dereliction of duty to maintain and enforce the Law and public order and safety.
Barely two weeks after this eco-millenarian cult withdrew,the following headlines sprouted up, a further clarion call for capitulation to the Vegan AlQaeda.
