Chief Constable Peter Wilson, who is in charge of the G8 police co-ordination centre.
We put on additional policing in support of Central Scotland Police just to provide reassurance to the people of Stirling that we were going to prevent, as far as we possibly could, any recurrence of the violent disorder we saw yesterday morning.
Now, I understand, some of the campers who we always intended we should allow to leave, provided they could establish that they were leaving for a peaceful purpose, are engaging with local police.
We recognise that many people travelled to that site for the purpose for which it was intended and it's been distressing that it's also become the focus for many of the problems that we've found throughout the last two or three days.
We're very keen that we make it clear that we reassure the people of Stirling that we are here to prevent any recurrence and I know the chief constable there is anxious that message remains throughout the day.
There were clearly some people who were there for peaceful purpose but clearly there was also many who came out yesterday morning with intent to cause trouble.
I don't think the public see us as being heavy-handed. I think the message that the public are seeing is we are there to respond robustly when it's necessary but we are also keen to ensure right across Scotland that it's peaceful policing.
Peaceful policing, that's very much the message of this service this week.
Dee Coombes, from Liverpool. A "Justice Fairy" who was involved in a road blockade on Wednesday.
The mood in the camp is calmer now than when the police arrived at half past two this morning. People were very frightened.
A lot of people have heard about violent protests and people being tear-gassed. I was tear-gassed two years ago when we went to protest at the Evian G8.
It is calmer but pressure builds up because people become very frightened when they're hemmed in like that and that's been a problem this whole week.
The police have put so much pressure on people that it's caused situations that needn't have happened.
I was at a roadblock but there was no violence involved, except for the police disabling our vehicle.
The road was blocked when we arrived there. We were there because we were trying to defuse violent situations and the police just decided that our vehicle was abandoned and disabled it.
We were searched illegally, there's a lot of harassment going on.
We had an enormous amount of support from the people in Crieff yesterday. We had people hanging out of their windows saying 'I've taken a video of this, you can have my phone number. We think it's terrible what's going on'.
One man came and started off by saying 'why won't you let me go to work, I've got my children to feed' and then he started telling us about protests he has taken part in."
