I think your chances of being shot and killed
significantly increase if you are involved in a crime, and multiply if you are Black or Hispanic.
I have lived with this rule all my life and taught it to my children. I'm sure his parents did the same. Tragically he chose to buckle under the pressure of negative voices, peer pressure, whatever.
Admittedly my children (who were not always angels) would have been way too chicken shit to attempt robbery, so I didn't have those worries. My kids chose liquor as the way to prove their maturity. My 14 ye old daughter turned my hair white one night when she didn't return home from a party and no one knew where she was. Turned out she was passed out under a friend's bed from drinking beer.
Are we not strict enough with our children? Do we we not spend enough time teaching them that crossing from childhood and entering an adult body means that someone might confuse you with a grown up? Might try to sell you drugs or rape you or shoot and kill you?
There is no doubt that the shooter was wrong, but are we doing enough to warn our kids? Are we doing our part to keep them safe?
