A place I took over before the previous director claimed that the administration wouldnt support them in discipline and told them to stop sending kids to the office. When I arrived I found out it was because they were sending the kids to the office for every minor infraction (i.e. not having a pencil, blurting out in the middle of class, eye rolling) instead of handling as much in class as possible. I, on the other hand, try to handle as much as possible in class with only sending kids to the office a small handful of times this year each with very supportive results.
So you have to remember that while some situations are bad sometimes the band director just wasnt a fit for that school
