Operation Spectrum

In the last few days, I have gotten a number of hits on this post. It seems that the Marxist Conspiracy arrests of 1987 have been a topic of much discussion in the wake of the death of Lee Kuan Yew.

In my blog posting I gave the impression that the entire government was in favour of detaining the so-called Conspirators without trial. In this article, we learn that at least one Cabinet Minister resigned in protest of the government's actions. I applaud his courage.
