It is what happens when quotas are needed to keep the staffing levels up. They have to look the other way, and allow all the chaff and wheat into the military and try to capture what shouldn't be in.

I wonder if there is a coorelation between violence, desire for being in the military and police organizations and some variant of systemic racism.

IT can be to do what this person did, or it could be to get away from it, or to help prevent it.
