There's certainly a bunch of interesting stuff in there, like how officers are instructed to place iPhone in nickel or copper plated containers in order to prevent remote wipes and a ton of information about gangs and smuggling.

There's also other cool technical stuff in there, like how they gather digital evidence, information about hacker forums like ryan1918.com that have information on FBI honeypots and a book on how to "crack leetspeak".

Unlike the other releases by LulzSec, this looks like it actually is an useful, WikiLeaks-style release (except they haven't filtered out any private or irrelevant information like Wikileaks tries to do)
