It's almost like it's a tongue in cheek comment about how whenever someone brown does something it's news of the highest order followed by arguments regarding immigration and "dem muslim terrorists", but whenever some random white dude goes on a spree it's just about how "the system failed him" or " he was sick" and how there's nothing really to be done about it (totally not a guns/mental health issue at all guise! Nuffin' to see here!)
But subtext is lost on the vast majority of the planet.
