That study computes that you're 7x more likely to get murdered in prison than in the "comparable non-prison community", but "comparable" here seems to be only for age/gender.

I imagine the homicide rate is a wee bit higher than average for drug kingpins, particularly those seen to have ratted out 100+ people, even unintentionally.

Yeah this guy presumably had a wide ranging network of people who he knows, who haven't been caught, but may be exposed ... by him. This dude now poses a risk to a lot of very worried people right now and presumably the people he relies on are running for cover / maybe less likely to protect him.

> "homicide rate ... is up to 7 times higher [than outside]"

This is based on assumption that a regular "free" person has not made thousands of criminals at the same time.

He would be going to Golbourn Gaol, very very high security.

Prison sure kept Carl Williams safe. Safe from dying of old age!
