Comcast's Law Enforcement Handbook (PDF) was leaked today and posted on Secrecy News.

Here's what it contains, in easy-to-skim bulletpoint format:

• Setting up a wiretap costs $1000, includes free month of surveillance, $750 for each additional month, all costs waived if it involves kiddie exploitation
• Can access call detail records for two years
• IP assignment address information kept for 180 days
• Comcast reminds law enforcement agencies of the specific statutes they need to follow if information requests have to do with people outside the country
• Proper procedure must be followed for using National Security Letters

Overall, pretty dry and hews well to statute.
