Insufficient data... You can’t keep banging the minority drum without specifics. For what abusive actions, for how long, etc. I’d bet that they only looked at specific targets to make their statements. That is always the way it happens. I’d also bet that minorities were the most egregious instigators also - not that you would know here...
“Insufficient data...”
You’re right; my children go to school with a bunch of minorities that are never disciplined (they get it at home - Indians, Orientals, Arabs). The only people getting disciplined are unruly whites (and rightly so).
It is impossible to obtain an education where a large number of “other minorities” are in the classroom - they are the worst environments filled with distractions as the hopeless pass time.
