Again, that system was tried: anonymity protected the Magistrates, but it didn't actually make the system work better.

The current system IS a compromise. The magistrates do have a secret forum for their internal debate, so people get to see the judgement of "the magistrates" and not how they voted individually. That gives them some protection since you can't point fingers at specific magistrates.
