To be fair to Lui Tuck Yew, at the very least, he has integrity to admit that all are not well with MRT. Unlike the General at SMRT who keeps claiming that all are well, Lui at least feels guilty conscience about the all the whole mess. However, a good Admiral should fight to the last bullet and sink with the ship, instead of running away. Change ship or ammo if you must, but you gotta fight till the last breathe. If Lui, a scholar and top talent of PAP cannot solve the SMRT mess, who else in PAP will be up to this task?
