David Cameron has said contingency plans are now in place for the use of water cannons if needed. On BBC News at about 11.45 this morning. Just seen it on internet site. So water cannons are possible after all.
I know that's what you mean, but why would Cameron say this, if it wasn't possible? By the way I know he's a politiican and they all lie, but surely people would expect water cannons if he promised them and more riots ensued ?
They want to tell people what they want to hear, so they are saying that they will allow water cannons to be used, except they don't actually want to use them.
Just a thought though, we have fire engines. A carefully aimed jet from a hose is (a) gonna soak em and (b) may knock them off their feet. Even a soaking is better than nothing though, and if you are wet through, then you were in the looting and riot mob.
