Unkind extraordinary rendition case (13)
I believe the answer is:
inconsiderate
'unkind' is the definition.
(thesaurus)
'extraordinary rendition case' is the wordplay.
'extraordinary' indicates an anagram.
'rendition'+'case'='renditioncase'
'renditioncase' with letters rearranged gives 'INCONSIDERATE'.
(Other definitions for inconsiderate that I've seen before include "intolerant" , "Heedless" , "showing no regard for others" , "Lacking thought for others" , "Without regard for the feelings of others" .)
