TEATIME...Yep something about that "disjointed splayed gait" implies alcohol to me, too. I read Texas does not sell alcohol on Sundays.I think SP walks like someone loaded on something, booze comes to mind.

Does that mean the SP is more likely to be local or from out of town? I continue to review the "body language" when SP looks into the camera and it is almost as if they are saying, "So what, I'm already here." Of course my post doesn't add one thing into identifying the perp, but I did want to acknowledge your opinion as VIABLE!
