...emphatically this is NOT the case.
I've mentioned before that I have family and friends who have children in those adjoining districts (and some of which I have observed first-hand), you have students at the grade school level cussing at teachers and staff while in the classrooms and halls and doing worse.
I can tell you for a fact South Lake, East Detroit and Lincoln have got discipline problems that need to be seen to believed.
Eastpointe for example, has the entire police department dispatched to "shadow" the students almost daily as they leave school around 2:30 and walk over towards Nine & Gratiot to board SMART buses or just walking back into Detroit. They also regularly cause problems at local businesses requiring several squad cars to remain on-site.
And when they have any sporting events (specifically basketball), do you know how many times the call to goes out for mutual aid because there simply isn't enough manpower to maintain order?
I don't have any problems with Charters, because they will at least maintain some level of conduct and don't have any qualms about kicking out those who don't follow the rules.
Publics, on the other hand, are scared you-know-what-less at holding those students to any kind of rules.
