I think he answered your question by providing an example on the spot.

I responded to what I regarded as a ridiculous question. I've said enough to indicate my view of the seriousness of false confession. Do you really find it difficult to believe I could come up with countless examples of behavior that, say, you and I would agree is mildly antisocial--my neighbor's failure to trim weeds that were partly obstructing our block's common driveway, for one? You're being pointless.
