Better believe it. It's my understanding they were putting their treasonous posters up on OTHER PEOPLES PROPERTY, as well as public property were such signs or any signs are not allowed. There was a photo, by (Mr)trooprally of one on what appeared to be a telephone company junction box.
But looking at it again, it might be the control box for the traffic light. Still off limits and subject to a fine, which they got. They are just trying distract from the "where" by referance to the "how" (soluble glue).
