Having spent a number of protest marches being told by the police where we can and can’t march or shout (no shouting in Parliament Square being the most worrying), I can’t help but find it amusing that the police are angry that they themselves are being told they can’t march past Parliament. I realise they are only doing their job when shepherding us, but it’s quite gratifying when the rules they spend their careers enforcing come back to bite them on the arse.
