Your phrase was “not unusual.” Does the existence of something happening somewhere disqualify that thing from being unusual? This is a conflation of the macro with the micro. Not unusual how? Not unusual that in any given week that the US, with 70 million children, has a child shooting another? That may not be unusual. Unusual for your child neighbor next door to shoot another child? Very unusual, irrespective of where you live (even if you’re in the worst crime-ridden area of the country — still unusual).
Brace yourself for this one, but every day in the US people win the lottery. I am thrilled to know that this is not unusual.
