Have second thoughts about prisoners getting free ride (10)
I believe the answer is:
reconsider
'have second thoughts' is the definition.
(I've seen this before)
'about prisoners getting free ride' is the wordplay.
'about' becomes 're' (regarding).
'prisoners' becomes 'cons' (short for convicts).
'getting' means one lot of letters go next to another.
'free' is an anagram indicator.
'ride' anagrammed gives 'ider'.
're'+'cons'+'ider'='RECONSIDER'
(Other definitions for reconsider that I've seen before include "Have second thoughts" , "Ponder further" , "Nice orders ( anag.)" , "Think again" .)
