Sometimes I'll listen in on police radios and you will hear officers sigh like, "Damn, not this shit again" cause they recognize the address they are being sent to for a call and remember the guy from just a few prior meetings.
And now these cops are being sent to the same couple over 40 times and are like, "Oh ummm gee, I wonder who these people could be".
I honestly think the real reason is that most of these cops want these calls to be true, because they get sold on the idea that being a cop is cool and about fighting crime when 90% of the job is super boring.
