Do your realize how many missing kid calls they get everyday, 99.99% of which are false alarms?
So you're a cop, you come to a house on a missing child call, you stand in front of the house next to an abandoned car talking to the single mother about her missing boys, it's obvious that the whole neighborhood has been walking past that car for the past three hours in search of the boys, so you don't search the car very hard.
And you want a policy for this situation?
Priceless.
What's priceless is that, given the stats made up, you don't think one is necessary.
