Ass is playing hard stupid.
Could be insane, could simply be a bus driver or other redirect, or, could be a lyncher, which seems to be to be a highly viable option.
I would more apt to lynch Ass than Scribble. Mainly because he wasted no time to wait and see if he could get info, see who is buddying up to who, etc and needlessly claimed cop early on. I real feel lyncher is what he is, that or stone cold stupid.
