Hacking outfit LulzSec has claimed responsibility for hacking into the website and database of the Arizona Department of Public Safety (DPS).
The outfit has released details of staff, emails and correspondence on public file-sharing sites causing many coppers to claim they have been receiving crank calls.
LulzSec said they had targeted the department in that state because of its tough immigration law, or in its words "the racial profiling anti-immigrant police state that is Arizona". The press release was written by a "an anonymous allied ship, not The Lulz Boat."
Arizona attempted to bring in identification laws in a bid to keep the state white, er clamp down on illegal immigrants, but found the laws were frozen by legal challenges.
A DPS spokesman told the Guardian that the agency's computer system had been attacked and was taking additional security safeguards.
LulzSec said on its website that it was releasing hundreds of private intelligence bulletins, training manuals, personal emails, names, phone numbers, addresses and passwords belonging to Arizona coppers.
It includes plans to infiltrate various gangs, cartels, motorcycle clubs, Nazi groups, and protest movements.
In a press release it said: "Personal details of military and law enforcement in an effort not just to reveal their racist and corrupt nature but to purposefully sabotage their efforts to terrorize communities fighting an unjust "war on drugs"."
LulzSec is saying that it can do a Wikileaks and start releasing classified documents and embarrassing personal details of military and law enforcement.
Rival hackers have been hitting the groups website and identifying its members. One, called The Jester, is outspoken about LulzSec and has posted what appears to be information about prominent members.
