Banning protests/marches simply wouldn't work. Everyone would ignore it and the police would have even more work to do than they would of had to do if they let protesters hold marches and protests.
?When you have got people willing to break the law in this way, what is the likelihood of them obeying an order not to march or complying with conditions on a demonstration?"
Also, with their budget being cut to an extreme extent. "planned cuts to the Metropolitan Police budget ? which will see it lose £330 million over the next four years".
It's not the protesters they should be clamping down on it's whoever is approving of these budget cuts. Without sufficient funds the police force is, as he said, getting strained beyond their capabilities. So in a way the goverment are screwing over our police force.
