We could start by abolishing this police union. When we make a new force under the completely new rules a new union would must be made with completely different people.The biggest obstacle we have to making any changes IS the police Union and the power the communities provide them. They are why this is as bad is it is now, so I am having difficulty seeing any way of doing anything without having to work with them in some capacity.
I will admit that I am at an advantage as I was police in France and not the States. Do not be fooled however that these problems do not exist in Europe. They are just smaller scale.
