I have demonstrated outside WT conventions. There are many stories I could tell about our experiences, but I will have to wait for another time. After three years at one convention our group (3 to 5) usually, decided that we might be doing more harm than good and stopped demonstrating at the conventions, at least for now.
While demonstrating, we were lied about, to police, we were called names, cursed, followed closely everywhere we went, men in cars with two way radios driving back and forth everywhere we went, others on the roof of the convention center with binoculars watching us every moment we were in the area (from car, demonstrating and back to car)
At two of the conventions they had hundreds of JW men line the entranceways from the doors to the parking lots, so that JWs could walk between the lines without being exposed to our signs. This against 3 demonstrators. Just a little humorous.
