amnesix# ls -l /sbin/shutdown
-r-sr-x---  1 root  operator  164612 Feb 13 17:39 /sbin/shutdown

Thus, only root and members of the operator group may use shutdown.
Since members of the wheel group can su to root, those may do it, too.

No. Make sure only people allowed to shut down the machine are members
of the above mentioned groups.
