The GOP didn't need a fence. They had the whole area around the convention center cordoned off, from two or three blocks back, so that the pathways from the hotels to the convention center were clear of any potential protesters. I went over there on Wednesday, and the closest I got was Fourth St. where most of the media was headquartered. That was about two blocks walk from the convention center, and that's where the wall was located. Beyond Prospect St. you had to have press or delegate credentials to get in. Interesting that you mention Concertina barbed wire. The chain link fence on the west side of the convention center in Cleveland has three nice rows of it at the top.

What a disaster.
