too late
This could be the last round of arrests as LulzSec are reforming as LulzSec PLC, thus any hacking accusations will be investigated by internal inquiry whose results will not be made public.
British police have arrested two men as part of a continuing investigation with the FBI into computer attacks carried out under the flags of the Anonymous and Lulz Security hacking crews. The men, aged 20 and 24, were arrested on Thursday in Mexborough, near Doncaster, South Yorkshire, and Warminster, Wiltshire, under suspicion …
I don't see your point as being particularly a bad thing.
I agree it would be better to get the ringleaders than leave them alone (although anonymous by self-definition do not have any leaders) but, to take your riot analogy, surely you would like to arrest the scrotes smashing windows and stealing bins as well as the scumbags directing it.
If you catch enough followers then not only do you remove any willing pawns for the leaders to manipulate but eventually you will find enough evidence to take the big cheeses down along with the mules.
IIRC we started at the bottom of the food chain with your bog-standard German soldiers and eventually worked up to the high command until Hitler was backed into a position where he was forced to neutralise himself before Ivan did it to him.
Or are you saying that in WWII we should have avoided killing / capturing any Axis forces that were lower down the chain of Command than Hitler himself?
On a serious note, this isn't an exclusive either / or situation: the filth don't have arrest rations such that after they have arrested X suspected Anonymous hackers they aren't allowed to arrest anyone else so arresting lackeys lets masterminds go free.
Obviously plod is going after the low hanging fruit first it would be stupid of them to do otherwise.
Interesting you say that.
The Sophos article on this story suggests that one of the arrested "guys" might be the hacker who went by the name "Kayla" in lulzsec, who as I understand it presented "herself" online as having the identity of a 16 year old Schoolgirl (but still not verified due to the fact nobody talked to her on Skype)
here is the link.
