Tempted to think that if, a big if, politicians were in any way mindful of the effect their activities had on the citizenry, and, another big if, they were in possession of at least the majority of their faculties, they might come to the conclusion that they were ever so slightly failing in their very first responsibility: that being the safety and security of all in this sceptered isle. One wonders just who is in charge. Water cannon is a bell-weather of rebellion against a tyrant or a precursor to civil war. Maybe it's a wake-up call.
Perhaps the so called riots of 2011 which for some seemed to be an excuse for absolute vandalism that had the effect of destroying businesses and leaving people unemployed require the authorities to have the means of quelling these activities.
And that vandalism you and I are paying for in terms of increased insurance premiums and the police liability for the damage.
On a lighter note, if they had water cannon in 2011 perhaps they could have stopped the vandalism and put out the fires.
