Due to programs like "CSI" the public thinks in a big city like NY our police are doing every test and working hard on every case until they solve it with the best technology.
In reality there are a bunch of items in storage such as rape kits they can't afford to process. And your average detective has a poor understanding of the high tech tools they could be using. They need more training.
Lastly detective case loads still suck. Murders shouldn't be a rush job.
Someone DIED.
