The one thing I can offer is, that the current Detroit PD chief previously served as chief in Portland, ME.

When he arrived in Maine, he was quite anti-gun. I'm quite close to the pro-2A community in Maine, and I can tell you that a number of people were very active in things like open-carry community service projects to desensitize the community (and LEO) in a variety of municipalities, especially Portland.

When said chief moved from Portland to Detroit, he became a staunch advocate of carry permits and civilian ownership of firearms. Hopefully the new Dallas chief observed the Detroit experience and absorbed some of it.
