BHO was the first Pres. candidate to get a SS detail, and they broke up a couple of meth addicts in Denver that were going to "get him" at 800 yds. A far fetched plan at best, but there is a bunch of agencies that anticipate potential problems with security for BHO, its a 24/7 job, and I'm sure its not easy.
The left will portray it as "gun crazy" people, but I hope it doesn't get to that level of BS.
