Najib should have learned a thing or two from old fart and his son.
Old fart squirrelled away $10 bil in secret Swiss accounts and property investments throughout the world without the Western press getting a whiff of it. He legalized corruption by paying himself and his cronies handsomely. He gave the entire HDB conveyancing to his wife's firm without an official tender. He maintained a mistress in Taiwan for more than a decade.
Najib murdered a Mongolian model in his own country. He chose to siphon $1 bil of state funds to his personal accounts in M'sia and got caught. How stupid can one get? All politicians know that you don't shit where you eat.
