Well hoo flipping ray. The government are at last thinking of deploying water cannons on the streets as a measure to deter the trouble-making rubbish that cause our valiant police men and women such heartbreak and physical abuse. I wrote to No 10 and the Home Secretary Kenneth Baker not long after John Major took over from Baroness (then Mrs) Thatcher suggesting how useful water cannons were in deterring the rubbish from making trouble on the streets of Northern Ireland. They replied that "no", not on my watch, i.e., "I've got an expenses scandal to built up to and the police have helmets anyway". While I realise that the average police-worrying trouble-maker on the street possibly doesn't wash voluntarily anyway (the two words they detest being "soap" and "work"), they nevertheless object to being soaked with water on a typically cold British night. So don't faff around Mrs May. Get cracking and help the police to help them...
On my soapbox again!
