It would be reasonable to assume that those 26% don't actually believe that the Malaysian government is, or has been, forthcoming about events concerning MH370, but represent the hard core supporters of the government who also support the obfucation of MH370 information.
Not being
forthcoming with everything that curious people want to know is not the same thing as "
obfuscation".
A classic example occurred in the past few days. A report emerged that the co-pilot's phone had connected to a tower in Malaysia. The journalist concerned characterised this as an attempt by the co-pilot to make a call, which is a different thing again. The Malaysia Transport Minister was asked if the report were true, and replied to the effect that he didn't know, but that in any case it would be a matter for the police, and that they would release such information if and when they saw fit. People on this forum then characterised
that as a "denial" of the original report by the Malaysia Transport Minister, which it manifestly wasn't.
So, was there witholding of information here? Yes, by the Malaysia Police it seems, and there seems no reasonable grounds for criticising them for it. Was there obfuscation here? No. Was there confusion, speculation, general silliness? Yes, by a journalist and members of this forum...
