Doesn't a serious investigation normally involve an investigation of people close to the suspect?
police department published them unredacted
Not FB's fault.
That may be, but it certainly makes a case for not using FB in the first place.
I'm also surprised it didn't contain private messages (I'm guessing you can do this on FB?).

What law? Which records? There are websites, such as those which provide anonymous web access, which say that they don't keep any records, or keep IP addresses only, or keep records for no more than 30 days, or whatever. Are they lying to us, or are they intentionally breaking some law? Exactly how can I be forced to keep any kind of log, for any period of time?

It's a really complicated legal issue, and the last thing you would want to do as an international company is shoot yourself in the foot by deleting "evidence".
"The United States does not have any Internet Service Provider (ISP) data retention laws similar to the European Data Retention Directive. All attempts have failed:"
THEREFORE: Under what law was FB required to retain the data, which was eventually handed over under subpoena?

The location of its legal tax headquarters is up for debate; Additionally, Facebook has corporate offices all over the world in different countries: https://www.facebook.com/careers/locations Italy, India, Canada, New Zealand, Belgium, etc.
Clearly it's not just a "US" company and only has to follow "US" laws.
But I think i remember something about Facebook having european offices in Ireland, so for us Facebook users in the European Union it's the Irish and EU laws they have to abide.
But I havent got a clue about what law regulates theese things.
