4Chan /pol users are casually trying to get black people arrested or killed this week. They've created several fake Nike coupons for "people of color" in light of the Kaepernick deal.
The QR code on one of them, when scanned with a barcode reader, displays a threatening message: The intention behind this hoax is that a black person would print out the coupon, take it to a cash register to redeem their discount, the retail assistant would scan it, and the black customer would -- without knowing it -- threaten to kill everyone in the store.
