When Malvo and Muhammad were roaming around Northern Virginia killing people they regularly called into the "command center" set up to receive tips.

They were just as regularly blown off.

The folks answering the phone wanted "tips", not "negotiation". I am sure the same sort of psychology was at work here. Besides, as it turned out, this really was a crank call ~ no shots had been fired that day.
