Dave,

Perhaps they don't know the answers.

It was a tragic event.

Death of a loved one is difficult to handle when normality prevails.

Government officials are only human.

Look at at other tragedies. For example the Sunami.

Do you think people got answers?

The Chinese earthquake. Do you think people will get answers.?

Twin Towers...............Do you think people will get answers?

The next tragedy.........People will not get answers. There are non. It really does not matter how many questions you ask.
