DU dismisses as insignificant what they fear. Contrary to early reports, it was found in an area used by residents, staff, and business guests of the staff. And contrary to what DU-folk want to believe, even a snack-size baggie is large enough to contain multiple doses. Snack or sandwich size, a baggie might or might not be obvious to a security camera, but the quantity of cocaine would be significant.
On the flip side of what the camera will show, it will show every resident or staffer who used the area in the previous day or so. That would be the suspects list, the starting point. Each person should be required to take a urine test, and each staffer's desk should be tested for cocaine residue.
Remind me ... what was one of DU-folks' favorite nicknames for GWB? Ironic, given when cocaine was actually found in the WH.
