Turns out that procedure is completely legal in Minneapolis, it's in their training manual! AJ had a former cop on his show today and showed the Minneapolis restraining rule book concerning leg restraint applied to neck. I'm starting to wonder if they can convict that cop for anything.
LAPD found out that having the not unrelated chokehold/sleeper hold being in their training/rulebook did *not* save officers from being convicted of manslaughter and murder when they had people die in custody.
