If it is true that former Singapore prosecutor Glenn Knight had wrongly prosecuted former MCA president Tan Koon Swan, then his apology to him is not sufficient, he is also answerable to the people of Malaysia and Singapore.
This is because his actions triggered a chain reaction leading to the collapse of the Pan-Electric Industries company and the disruption of the stock exchanges in Singapore and Malaysia.
This in turn caused losses and operational disruptions to many public listed companies.
The incident might have even imposed a negative impact on the development of cooperatives, hence depriving opportunities for common citizens like hawkers and small traders to further expand their businesses.
An apology to Tan Koon alone is not enough. Knight still owes the people of Malaysia and Singapore an explanation.
