A crime rocking a country (7)
I believe the answer is:
america
'country' is the definition.
(America is an example)
'a crime rocking a' is the wordplay.
'rocking' is an anagram indicator.
'crime' with letters rearranged gives 'meric'.
'a'+'meric'+'a'='AMERICA'
(Other definitions for america that I've seen before include "West Side Story song" , "The USA" , "Race aim (anag)" , "World power" , "The US" .)
