Can't get arrest records, but criminal records are there. I know someone who was just sentenced (January 31 2007) to 4mos prision in NYS, his record doesn't show up. But, a guy I know who did 2 years for a DUI in 96 shows up. So, I'm not sure how recent that is.
Then again, for most current crim records (at least for NYS) there's the Unified Court website that takes you to the timeline, etc.
You can find divorce proceedings and some other stuff under cases.
