Unfortunately, without a team of security officers patrolling at all hours or a real use for the building to be inhabited, I think a fence will be necessary for some time to come. YES, it will be nice when one day it doesn't need a fence....but I'm sure they don't want to see their investment destroyed by a couple idiots with a pair of wire cutters and a plan for destruction.
If they're smart, they'll spend the bucks and install a fence like this:

They're much harder to get through than chain link and yes the photographers can still poke their lenses through the slats for photos. Also, assuming they continue their smart-streak, they'll put plexi-glass covers over the lower window panes as a temporary measure, to curtail the damage of any future rock throwers....
