The Restless Sleep:

"If you want something done , ask a busy person."

Interestingly, when the murder rate was at its highest in New York, so were the clearance rates. In the 1980’s, the percentage of murders that went unsolved in New York was 31.2%. Now it's up to 40%. (It's been hovering around 35% for decades, sometime a little better, sometimes a little worse.)
