I could walk around sudo!!!

I am just installed sudo in my system. and played around with it. I just
feel that sudo can not protect anything. Here is am example:

1) no protection for Log file : I can easily delete the enties in
/var/log/sudolog by " sudo vi /var/log/sudo" or "sudo rm /var/log/sudo".

2) Can not block certain command : 

even su is blocked by the sudoers:
Cmnd_Alias      TEST=/usr/bin/su

# User privilege specification
root    ALL=(ALL) ALL
%sunteam ALL=(ALL) ALL,!TEST

I still can su to others by creating a simple script. here it is:
$ more sudotest
/usr/bin/su $1

Same script can be used to do any thing!!!

How can you block this?

I looking forward to your response!

Best Regards
