Anonymous hackers associated with the AntiSec movement have downed at least 70 law enforcement websites.
The hackers also managed to extract "massive amounts" of confidential documents, including email spools, usernames, social security numbers, residential addresses, phone numbers, password dumps, classified documents, internal training files and informant lists.
"The leaked data contains jail inmate databases and active warrant information. [However], we [will be] redacting the name/address info to demonstrate how those facing the gun of the criminal injustice system are our comrades and not adversaries," AntiSec explained in an official communiqué.
"On the other hand, we will be making public name and contact information about informants who had the false impression that they would be able to 'anonymously' snitch in secrecy."
The hackers also warned law enforcement officials that "bogus, trumped-up charges" against individuals linked to Anonymous PayPal LOIC attacks would "not stick," nor would "intimidation tactics" serve to stop AntiSec from exposing government corruption.
"While many of the recent 'Anonymous' arrestees are completely innocent, there is no such thing as an innocent cop, and we will act accordingly. In our fight for a world free from police, prisons and politicians, we will continue to expose their corruption and destroy their systems.
"To our hacker comrades: now is the time to unite and fight back against our common oppressors. Escalate attacks against government, corporate, law enforcement and military targets: destroy their systems and leak their private data. Remember, there are more of us than there are of them, and they can never stop us all."
