In November 1999, a Deming mid-schooler, Araceli Tena, was mistakenly shot and killed by a 12 year-old classmate in a school corridor full of students. Nobody knew what was going on, but it was resolved without further blood. During the hectic 3 or 4 hours afterward as we were trying to account for all students and get them to the right parents, a Wal-Mart district guy from El Paso kept calling. When he finally got to talk to an assistant chief, he got permission to send (flown in from all over the country) a post school shooting trauma team, counselors, and a pocket full of cash for food for a community meeting that night. They as well picked up the (uninsured) girl's medical tab and funeral.
Wal Mart had no store in Deming at the time; the one condition for all the help? That NO ONE revealed the source of the assistance officially and that city officials discouraged gossip about it.
I shop at Wal Marts whenever in-country.
