Yes the violence was limited to the Manchester demo.
Todays demo in London was a nice day out and I'm very glad I went.
Must have walked several miles in all, rather sore on the feet.
Here's a few videos I took on my blackberry...
Some people were certainly having a good time:
A rather carnival atmosphere:
At one point later in the demo, some flares were lit, but no violence. The crowd stopped for a minute or two, then continued walking the agreed route.
I notice the BBC used the image of this event for their story caption...tut tut.
No other flares or fireworks were lit that I saw.
On a side note, it was nice to get talking with the police on several occasions, very good spirited chaps.
