Basically Nartwak, you see a picture of lots of kids throwing things at people, then shortly after the British soldiers come running after them and grab a few of them. They bring them back inside the base/headquarters/whatever, and beat them to the ground, then stick handcuffs on them.
I think I'm with you on this one Walsingham, I do find it quite disgusting that they can just beat these kids up quite so brutally, I mean, couldn't they just arrest them and hold them up somewhere to teach them a lesson?
The kids may have been pelting them projectiles and whatever else, but I see that as no reason to beat them senseless.
Edited for spelling.
