Now I do. It just validates my advice. Getting rid of the shoes saved his sorry ass, though you could have had video of the decapitations and that jury would have acquitted.
Based on OJ's close call I probably should revise and extend the advice: Months or years before the act, buy a treadless pair of shoes with cash. Make the time of the killing the first and last time you wear them.
A treadless shoe still has a tread. Just with no lines or squiggles.
Maybe track spikes are a better idea.
