I hear a lot of whining about turbos from people at work, and the bottom line is they're coming from a place of ignorance and darkness.
We run a fleet of about 40 5.4L F350s and their durability is frankly amazing. They're all 2004/5s approaching an average of about 60000 miles, but that's completely urban, very long idling, and nothing but stop and go. They are starting to use oil, about 1 qt/1000 miles on 3k OCIs. It used to be 1.5k OCI until the budget tuned sour.
I think for fleets that auction by 80-100k, turbo (and overall) reliability won't be an issue. As long as Ford has figured out how to disapate heat, and I'm pretty sure they have, there's no reason for a turbo to fail. If they're running coolant after-run pumps like Audi, or have other related hardware in the engine bay to manage heat, that's where I would expect to see problems.
Police service tends to abuse the suspension and bodywork more than the drivetrain. Even the [censored] Impalas didn't have engine problems.
