I believe that sudo can be configured to limit the extent to which the
proviledge is used, in other words you could probably set it up to
allow your users to do what they need but not to delete their tracks
eg. bash_history.or rm /var/log/*
I cant say I have done this myself but I did read man sudo a while
back and such things seemed possible.

ps. If you know what specific authoirty you wish to grant rather than
all except xxx it may be easier to so this.
