Yes, it would... if he was not at work his entire shift, came in late and/or left early, then that would become part of the investigation, and they would be reminded not to reveal that information publicly. However.... IF he was at work his entire shift, and did not leave at any time during his regular hours, thus providing a solid alibi, then PDM could certainly state that to the public when asked and LE would have cleared him a long time ago. By these work hours being questioned and PDM firing him back in April, tells me there is some suspicion there and he is unofficially a POI. I see no reason whatsoever for LE not to clear him publicly if this so-called alibi does exist. IMHO.
