deleting files

[Raoul Armfield]

I am having some issues deleting certain folders either from the finder
or from the CLI.  I get permission denied errors.  When I look at the
permissions I am the owner and have read/write permissions to these
folders.  However, I notice that there is a little lock symbol on the
folder and the locked box is checked off and greyed out thus I am unable
to unlock it.  

Anyone have any ideas on how to unlock these folders?
