Listening to the BBC coverage, Kit Malhouse has just confirmed that we don't own ANY water cannon and that he is 'reluctant' to bring in the army.
I'll bet that the people trapped in that hellhole or who have had their homes or livelihoods destroyed aren't feckin' reluctant so pull your head out of your arse and do something.
After all, we may not have water cannons but there are nearby bases that have military fire engines which can do pretty much the same job.
