Well, IMHO every case is different and driven by evidence. Why issue a BOLO (be on the look out) if you cannot be VERY specific. For example, BOLO's are issued in an amber alert, when vehicle specifics are known. Here we have a vehicle that may or may not have anything to do with MB or Creekside Church. LE is being cautious and not making any (even if logical) ASSumptions.
