Hmm. . . outside possibility, that they simply bought the stickers for cheap somewhere. I’m thinking Chinese quality control here. Certain adhesives ARE irritants.
Not saying it wasn’t planned, but could well be simple stupidity on several people’s part. . .
One of the cops I know who was working the RNC sent me a text yesterday saying officers were getting sick if they touched the stickers without gloves. I haven’t actually talked to him so I don’t know if he saw it first hand or was told. He also said they were using darts to sicken officers as well.
