I'm not sure why you'd be downvoted for saying that, it's not objectionable...

But it might miss the point. Someone convicted of burglary may have been burgling to get money for their addiction. That may or may not be recorded. Although you might be right, maybe that sort of stuff is routinely recorded. I have no idea!

The BJS studies it:

I'd guess if they have court transcripts, or some kind of description in a plea deal, it's possible it was mentioned. That might be valuable data, but having a person scrape through that data would take ages.

I too am confused why I was down-voted, but i guess you can't please everyone :\

Don't need an AI, just use a statistically valid random sample, then use human intelligence to analyze that smaller data set.
