I don't know much about CMS leadership these days, so I don't know what kind of resources, experience and/or knowledge they have to throw at things. But I do know they lack spine...the last couple of times they've tried to figure out Myers Park, South Meck and Ardrey Kell, they've quickly dropped it after public outcry in the areas affected. I think wealthy parents in those zones are controlling the school boundaries as much as anyone else these days.
As far as crime goes, it's just like any other city. There are places where you don't need to lock the doors, and there are other places where you need to bar the windows. The newer sections of town, though (Ballantyne, University, South Park...the places where Mallard Creek, Vance, Butler, Ardrey Kell, South Meck, Myers Park, etc. are all located in) are really, really nice. I'd be happy to live in any of those areas.
