This was just reported to me by a friend who vends at Cowboy Christmas and was staying at South Point. He was walking back to his room from the sports book, when he saw a little old man bent over in front of a row of video poker machines. He was rubbing his butt and sobbing. A security guard stopped by and asked him if he could help. In response, the old man screamed "You're all liars" and told the guard that his "kind" was "destroying the country." The guard gave up and walked away. (My friend didn't report the race of the guard.)
Based on when this incident happened, this preceded David's first threatening post (of this year, that is) by several hours. Coincidence?
