Serious question lingers over Najib's Premiership!

This is an interesting article in Malaysiakini!
I thought I highlight a very interesting section from it!
These are unanswer question that are very worrying!

Private investigator P Balasubramaniam and his entire family mysteriously disappeared a day after he revealed a sworn statement giving intimate details incriminating Najib to the murder case in July 2008. Despite promises to investigate, the police have remained silent over the contents of this affidavit. And the court had also barred the admission of this document.

Why did the police and the court keep a safe distance from this document that could have led to a breakthrough of this trial?

What has happened to Balasubramaniam and family – as nobody seems to know their whereabouts?

Why further evidence by Altantuya’s cousin Burmaa Oyunchinmeg when she testified that Najib appeared in a photograph with Altantuya blocked?Why did the court block further evidence upon revelation in court that Malaysian immigration records of Altantuya and her two Mongolian companions had been mysteriously erased?

Shouldn’t such erasure have been considered an important lead and an indication that some VVIP was involved?

Why were Najib and his aide-de-camp Musa Safri not investigated and called to the witness stand, since it was Musa who gave instructions to the first accused (first and second accused were Najib’s bodyguards) to solve third accused Abdul Razak Baginda’s ‘woman problem’.

Now that Razak Baginda (a close associate of Najib) has been declared innocent, we are now left with the bizarre scenario of a murder without a motive, since the first two accused had no motive on their own to kill the victim.

What will this mean for the 2 accused?!?!

SCARY!!!!!
