What exactly does that mean?
I said that the organisers weren't likely to be on the train themselves.
...and I'm letting you know (again) that the these actions were organized by the people who carried them out.
XR actions, particularly actions which carry potentially long prison sentences are organized and carried out by small groups of people (known as affinity groups).
In this case, there was some consultation with the wider XR community about taking action on the underground, through a poll .The poll result was greatly opposed to this kind of action going ahead. I also understand that there were a number of conversations with members of those affinity groups, in which other people advised them not to go ahead.
One of the strengths (and weaknesses perhaps) of XR is that there isn't a central committee or figure giving orders - affinity groups are free to act independently as long as they follow the agreed XR guidelines (non-violence etc)
These 2 particular small groups decided to organize and carry out the action themselves, even though they'd been advised not to by a whole bunch of other XR folk, and then to add to the problems, one of them panicked and kicked out at a commuter trying to drag him off a train - not good for commuters, not good for XR, or the planet.
Hope that helps clarify.
