This quote by Pat Brown suggests that using MO (modus operandi) to link criminal activities can be a tough and undependable procedure. MO is a Latin phrase meaning "mode of operation" and is utilized to explain the techniques and methods used by wrongdoers to devote a criminal activity. It is typically used by police to link comparable crimes to the exact same perpetrator. However, this procedure can be bothersome because lawbreakers might change their MO gradually, or use different MOs for different criminal offenses. In addition, bad guys might use similar MOs as other wrongdoers, making it hard to accurately connect criminal activities to the same perpetrator. For that reason, utilizing MO to link crimes can be a difficult and unreliable process.
