In a non enforcing mode you will get a lot more messages than enforcing 
mode, since the kernel is just logging that if you were in enforcing the 
access would have been denier. 
So if an app was going to try to read a bunch of files in a directory, 
and got a denial on read it would stop in enforcing mode, in non 
enforcing mode it will get a denial for each file in the directory that 
it reads.

That is the goal.  This of course would be if the user and apps don't 
try to do something that they are not allowed to do.  IE if you install 
a fresh system in enforcinf mode and
cat /etc/shadow you will generate an denial message.
