* They performed an experiment that showed that having a single security guard patrol the parking lot at night completely eliminated crime (mugging, car break-ins, etc. that occur with regularity in Wal-Mart parking lots), but they did not put it into effect to save what? $75,000 per year?*

When was this last true? Where is this true? I've been to a half dozen Walmarts in North Texas which, I believe, all have security patrol in golf carts or old sub-compacts. At least the three I frequent do.
