"police officers in Florida have an x2-x4 higher rate of domestic violence" isn't quite the same as saying all police officers are out there to beat up whatever person they encounter in their day to day lives. They're still people and they still need social skills even to be able to work with their bosses and co-workers. For example, I've met a pretty tough police officer in a Toastmasters club who I'm sure could under some circumstances be very assertive but at the same time can obviously interact with people like a normal person under other circumstances. I've also met plenty of non police with hot tempers and violent tendencies.

Anyhow my point is the outcome isn't pre-determined and you have some ability to influence how things go by using some people skills.
