Also, there are so many criminals involved in the conspiracy that it is a waste of resources to convict peron X of so much stuff that they get sentenced to 1372 years in prison. Especially when person X is not likely to live for more than 20 years. Better to convict person X of just a few mundane crimes that get a 20 year sentence. Even if they do survive and get out in 20 years, there will be so much written about their crimes that they will be lynched on the street, and all their old gang will be gone.
In fact, if you start at the bottom of the criminal network, and take out all the worker bees first, the queen bee will lose the ability to operate and may just commit suicide and save us some court resources for other bad guys.
The whole story will eventually come out, and half the perps will be killed in prison by other inmates when they learn the sick shit they have been involved in.
