Why is Malaysia hiding the truth about the Iranians?

Photoshopped Iranians?

Things are getting a bit crazy here. These are the two shots of the Iranians using the stolen passports.  

These two photos are photoshopped.  You can see clearly that the lower half, the legs of the two guys are the same. They are both wearing the same green pants. 

Here is a blow up of the feet from the two pictures. They are both exactly the same : green pants with white shoes (a little pointy like ladies shoes). No argument these legs in these two pictues are the same.

These two pictures were held up by our people at one of the Press conferences.

Can someone please explain? What is going on here? Our country's credibility is at stake.
