"Another way the Devil can gain popularity is working in the realm of law enforcement. It is well-documented that mediums do help with finding crime victims."
Actually it is well-documented that police, when at their wits end in trying to solve a case, sometimes, rarely, have resorted to asling aid from psychics. In most of these cases the psychics provide no useful information. The few times that they do help get publicized way out of proportion. Stop watching so much "Medium."
"How appropriate that the devil would know where and how filthy and deadly sins were committed."
So, you are saying that your good and loving, omnipotent, omniscient "God" doesn't know? I mean, after all, he is the one who let those "filthy and deadly" acts be committed.
"I'm sure he keeps a chronicle of the deadly sins, over which he holds sway.
Satan keeps a diary?
"He also must feel like the victotr as his sinful cohabits are accepted in the law enforcement of today. In that he receives credibility."
So, you're saying that the police are Satan's lackeys?
"Cohabits?" What the heck is that?
