Telemarketing Call

what we can possibly do when we get "those" calls..The phone rang as I was sitting down to my evening
meal, and as I answered it I was greeted with "Is this
Karl Brummer?"
Not sounding anything like my name, I asked who
was calling.
The telemarketer said he was with The Rubber Band
Powered Freezer Company, or something like that.
Then I asked him if he knew Karl personally and why
was he calling this number. I then said off to the side, "Get
some pictures of the body at various angles and the blood
smears." I then turned back to the phone and advised the
caller that he had entered a murder scene and must stay
on the line because we had already traced this call and
he would be receiving a summons to testify in this murder
case.I questioned the caller at great length as to his name,
address, phone number at home, at work, who he worked
for, how he knew the dead guy and could he prove where
he had been about one hour before he made this call.
The telemarketer was getting very concerned and his
answers were given in a shaky voice. I then told him we
had located his position and the police were entering the
building to take him into custody, at that point I heard the
phone fall and the scurrying of his running away.
My wife asked me as I returned to our table why I had
tears streaming down my face and so help me, I couldn't
tell her for about fifteen minutes. My meal was cold, but it
was the best meal I'd had in a long, long time.
