Security is very good there. Everyone goes through a magnetometer, bags are searched, and mean guys are standing by with machine guns to deal with trouble makers. It's a damn sight safer at the Wall than it is at our airports. And recent observations indicate than tourism is not a problem.
BTW, last month I witnessed a dust up between Arabs, I think. It wasn't AT the Wall, but it wasn't far away, outside the security area. It took around 15 seconds for an Israeli military guy to throw the offending Arab against a wall and completely subdue him. One of his friends then started in and he was similarly subdued. I thought it was interesting that neither offered any resistance. After calm was restored, everyone was just permitted to continue on their way.

“offered no resistance” Very funny. I doubt that I would either considering that just about every IDF soldier operating in Jerusalem carries an AK-47. From what I saw on my visit, nobody messes with the IDF.
