They're actually arguing that knife fights are common among our nation's youth, without much consequent harm/deaths from the fights.
You have to wonder how unmoored from the realm of sanity these people are.
Of course, what they're doing is reasoning backwards. In every situation like the Columbus incident, the (racist) cop(s) MUST!!! be guilty. The black person/perp is never responsible for what they do.
Therefore, kids engaging in knife fights is a common practice/good clean fun and must not to be interrupted by racist cops.
Total blooming insanity.
