I wish I'd thought to ask for a phone number from the lovely couple who gave me a lift home in their cab last night at midnight as we attempted to skirt around the riot.
I know I thanked them. But I was shocked to the core to find riot police gathering at the end of my quiet, leafy street.
I hope they - and the cheerful black-cab driver - got home safely.
And I wish that the BBC would stop talking about protestors.
Because nobody was protesting.
They were looting.
