Pure speculation I know, and perhaps I'm reading too much into it, but when I hear words that have clearly been carefully chosen, and that clearly leave a loop-hole, spoken by a politician, I take notice.
That's the way all politicians speak these days about anything.
Interesting series about language on TV tonight and one example used was the appology. They are never sorry for saying anything, they are sorry that the words caused offence. It's quite a difference!
