No, I'm pretty comfortable blaming lawmakers for this. It's their job to keep the laws up-to-date, and they've failed in this case. It isn't random people on the street locking these kids up, except by a very extended and tenuous (albeit real, but still, small) connection, it's the lawmakers who keep it illegal without regard to human costs, who would rather send teens to prison and blaze them with the closest thing our society has to a Scarlet A (and ours is in many ways worse, certainly harder to escape), rather than risk their reelection prospects, who are to blame.

It may feel more gratifying to blame it on $DUMB_YOKELS, but given that this problem seems to exist everywhere regardless of their influence, it would seem to be an emotionally-driven decision, not a logical one.
