A public inquiry into which ministries dropped the ball for the pandemic, ought to happen before any election

As news breaks that Singapore now has the highest number of COVID-19 cases in Asia outside of China and India who have far larger populations, the Singapore government is quick to point out that it was doing all it could, distancing itself away from blame by stating that it did not have the benefit of hindsight.
Using the term “hindsight” may not be entirely accurate in this situation and could be viewed as an excuse to skirt some degree of accountability in this.
In the Singaporean context, our foreign worker accommodation situation was already found wanting prior to the outbreak of COVID-19. Migrant rights groups like TWC2 have long drawn attention to the cramped and overcrowded conditions.
Secondly, reports of migrant workers getting infected by COVID-19 were already made public in early February.
Thirdly, the knowledge and infections spread in close proximity is not rocket sense. All in all, these were known facts. Not hindsight issues.
So while the world (including Singapore) was taken by surprise by COVID-19, there were things that could have been done to reduce the impact of an outbreak based on the above that were not hindsight issues.
Dr. Jeremy Lim, medical doctor and co-founder of AMiLi, the region’s first microbiome bank and sequencing service has said that it was his opinion that the government had “underestimated the velocity and the severity of COVID-19 racing like wildfire.”.
Former diplomat Bilahari Kausikan has also alluded that the government had “dropped the ball” in relation to the recent spike in infection rates in Singapore.
Between hindsight and foresight, there lies a need for a certain degree of accountability that the government has so far not apparently acknowledged or apologised for. There are things that it could not have known.
However, there are also things that it did know and/or ought to have known. While Singaporeans do not expect the government to take responsibility for what it legitimately did not know, it is reasonable to expect the government to take responsibility for the latter.
When all this blows over, will there be a full fledged public inquiry to dissect what could and should have been done better? Will there be a discovery exercise to investigate which ministries did indeed drop the ball?
Without such an inquiry, it is difficult for any learning to be integrated because you cannot learn without first acknowledging your mistakes to the people who are paying your salaries.
As the ruling party is steering towards a general election within the next few months but the question is whether such an election should be held ahead of such an inquiry? Particularly if we recall the Hepatitis C saga in 2015, where a major lapse was revealed only after the conclusion of the general election due to a long chain of events and internal investigations conducted.
