It's logical to plan for massive events such that you won't disrupt the lives of hundreds of people. Manila City Government, I'm looking at you.

I was able to witness that sheer number of commuters in Manila walk the streets not in protest but in resignation. They just have to walk home or at least far enough from that massive clog so they can ride a jeepney towards home.

Also, you don't allow any organization to use a venue if you know for a fact that that venue will not be able to contain their desired number of attendees.
