I saw them earlier this week (excellent show) and that's a big, complex stage they have. I'm assuming something went wrong during the assembly of it.

That's tragic, though. My thoughts are with those affected by this.

Radiohead bring their own hanging gear and riggers, but the local steel looked pretty wimpy for what they were doing. Looks like regular old construction scaffolding, and it's probably been well used. Radiohead hangs a lot of stuff. Four (or more) huge posts are needed for this sort of weight. I've built stages and rigged shows. You have to have your wits about you at all times. Someone should have called the thing off for being unsafe, just by looking at it. Stricter regulations, along with inspections on these events is long overdue.

You're right about more inspections and regulations for these kind of things. This kind of stuff is happening too often at concerts nowadays.
