Anonymous Hackers take down the Texas Police Chiefs Association website on this Thursday.  They Defaced the main web page.  At the same time, they leaked the database sized 3GB .  

part of Anonymous message :

In retaliation for the arrests of dozens of alleged Anonymous suspects, we opened fire on dozens of Texas police departments and stole boatloads of classified police documents and police chief emails across the state. During the San Jose courtdate we defaced and gave out live backdoor and admin access to the website TexasPoliceChiefs.org while allied ships launched ddos attacks upon Justice.gov and other law enforcement websites. For every defendant in the anonymous "conspiracy" we are attacking two top Texas police chiefs, leaking 3GB
of their private emails and attachments. Mind you, we don't expect a sane response. Even a few insults would have been better than the way you cowards hide behind protocol, innuendo, and your badge.

They leaked the file in torrent also.

This is what they said about the Data Leak:

Thousands of documents are available on tor hidden services / bittorrent and include several dozen FBI, Border Patrol, and counter-terrorism documents classified as "law enforcement sensitive" and "for official use only". The emails also included police records, internal affairs investigations, meeting notes, training materials, officer rosters, security audits, and live password information to government systems. The private chief emails also included several racist and sexist chain email forwards and personal details sure to embarrass, discredit, and incriminate several of these so-called "community leaders".
