I imagine we have all noticed this feat in action countless times. I would point out that is not yet perfected by the TSA, near as I can tell. I once flew from Salt Lake to Maryland, wearing a sport jacket, and got through all security scanning, only to find a box cutter in my pocket, circa 2006!
Now if we could somehow evolve our brains to scan for corrupt politicians (I realize this would drastically reduce eligible candidates), we just might continue as a species. |
