Police chiefs will be pro or anti whatever the mayor, governor or other appointing authority is. They serve at their pleasure, and are usually gutless whores.
The attitudes amongst the cops that do the police work vary. As the police forces get younger(compared to me), less are inclined to support citizens packing due to the brainwashing they have been receiving from the public schools, TV, etc.
Most cops of my generation had no problems with honest citizens packing. We chewed butts on occasion(citizen grabbing handgun out of glovebox to get to registration, for example)but most of my peers had no problems.
