Carrying Identification seems common sense to most of us, but sadly some “para-sites” miss this fact. So why carry ID? Simple most investigations are done by necessity in the off hours especially ones at public locations and i’m sure any passing law enforcement officer will look into strange lights/people 😉 from a usually empty building to make sure no one is robbing the place. Besides that type of scenario, IDS should be available to show clients/owners you are who you say you are. You want to be professional or taken as such? Then don’t act shady. Simple.
