Families of passengers, crew of Flight 370 frustrated with Malaysian government

(CNN) – It has been a grueling 29 days for those with loved ones aboard Malaysia Airlines Flight 370, and not just because so little progress has been made in the search for the plane.

There is also growing frustration with the Malaysian government for what many perceive as a lack of cooperation to keep families looped in on certain aspects of the investigation. Many are asking whether it has something to do with incompetence on the part of government officials, or if they have something to hide.
