Well then maybe that's the cost of it, the public scrutiny of touchy things and political responsibility to justify such endeavors. It's like accountability is a bad thing.

If politicians would refused that, then that's a problem of politics, not of transparency.

I do understand that some subject might be too difficult to explain to the public, but that's more of an annoyance and extra work then anything else. Also could be a symptom of a education system with a lot of problems.
