"We're looking into it. And of course we're taking additional security safeguards."/ppOn 24 June, Lulzsec announced that it was putting 400MB of documents on the Pirate Bay file-sharing website a href="https://twitter.com/#!/lulzsec/status/84032144283938816"via a short message on its Twitter feed/a and a href="http://lulzsecurity.com/releases/chinga_la_migra_1.txt"a statement on its website/a. /p pIt said that AZDPS had been targeted because of its role in upholding the Support Our Law Enforcement and Safe Neighborhoods Act, also known as SB1070./p pThe legislation, passed in 2010, forces legal aliens to carry their ID documents at all times. It also obliges Arizona police to check those papers when they have a reasonable suspicion that a person may be there illegally./p pAs a border state, Arizona is particularly affected by illegal immigration.
