Sharon wants UN fact findings?

First, Sharon said that he would welcome a UN Jenin fact finding team because the Israelis had nothing to hide. Then he proceeded do the following:

1. Sharon asked to control the choice of fact finders
2, Sharon demanded that military people be lead investigators
3. Sharon demanded that he controlled who would be interviewed
4. Sharon asked that his witnesses be given immunity from war crimes charges
5. Sharon demanded that the fact finding scope be llimited in time
6, Sharon demanded that the fact finding be limited to Jenin
7. Sharon demanded to view and edit report before publication

It seems to me that Sharon may have terrible atrocities to hide. If not, why all the self-serving roadblocks.
