As far as I know, and have read, no, the cyclist wasn't going the wrong way, and hadn't jumped any red lights. There's a suggestion that she was using a phone at the time, and not demonstrating sensible roadcraft, but I don't know, so can't say for sure.
I can see that there will have been a meeting over the past few days, and the Police will have thought 'We need to be seen to be doing something', but I completely agree - doing some spot checks on motorists wouldn't have gone amiss. Although you can't direct a tipper truck onto the pavement, and so difficult to do without causing disruption.
