"1. Obviously someone was recording else this would not have made it to youtube...." It looks to me like the Anons were paying for vidsex girls, they probably recorded such sessions out of habit. One indicator is the chatroom tag given to one of the girls - "asshurtmacfags" - is not the type of handle a haxor would choose. Plus the "asshurtmacfags" girl looks human. I'm guessing the Anons probably used stolen credt card numbers for such "entertainment".
"......2. If someone is recording, why?...." See above. They don't get out much.
"......3. If you are dumb enough to be ON VIDEO showing yourself why be part of of a group that claims to be anonymous?...." If you're dumb enough to associate with people that do opiates and threaten FBI agent's families, and then actually pariticipate in criminal activity with such morons (and yes, what the Anons do is illegal), then you are dumb enough to video yourself. The only one demonstrating the tiniest bit of sense is the guy wearing the Anon mask. It won't help him much when the FBI go through the chatroom records and trace his IP. He may have been smart enough to use a proxy, but then again by associating with Brown he hasn't really demonstarted stellar intellect to start with. And I bet Brown had plenty of incrimintaing evidence on himself and his Anon/Anti-Sec buddies on his systems because he was so obviously drug-addled.
"....4. Someone was telling them in the chat that they should disconnect, yet they all wanted to stay online and watch the "bust"....." They're skiddies, or probably with drug problems going by the example of Brown, what did you expect? They're very obviously not Einsteins.
"....5. Only one person on video appeared to be hiding their identify yet all others were fully viewable and one even appeared to be showing herself off....." One smarter one hiding his identity, the vidsex girls probably didn't speak much English hence they just carried on during the raid.
There's a street "law" that says that every time you commit a criminal act, your chance of gong to prison goes up exponentially. Every time you share your criminal activities your chance of getting caught gets multiplied by the chances of the people associating with you. Their chance of getting caught (and yours) is exponentially increased by them doing drugs, using prostitutes, or using stolen IDs or credit card numbers. By the maths, Brown was a certainty for jail, and the people associating with him are now massively more likely to do jail time.
