Topiary: did police arrest the wrong man in LulzSec investigation?

Even if the police did arrest a member of LulzSec, none of the other members of LulzSec are going to admit this until they have no choice (assuming that they are fairly intelligent and not going to throw him away out of spite, which would be somewhat dangerous unless they are certain that he doesn't know the identities of any of the other members). It is in their interest to be surrounded by as much mystery as possibly, if they admit that the person was a member than prosecuting him becomes somewhat easier (as the prosecution wouldn't have to demonstrate that he is who they claim he is), and - true or not - the suspicion that they were able to misdirect or fool the police makes them seem more dangerous, and may make officials more cautious about future arrests.

"If you ask me, is the man they arrested in the Shetland Islands is Topiary, another hacker (either working in league with Anonymous/LulzSec or opposing them), or entirely innocent.. my simple answer is I don't know."

Should have put that at the top to save me a lot of time reading that drivel.
