A bit more, but not all about that one facing charges? (7)
I believe the answer is:
matador
'one facing charges?' is the definition.
(a matador is charged at by bulls)
'a bit more but not all about' is the wordplay.
'bit' becomes 'tad' (both can mean a small amount).
'but not all' means to remove the last letter.
'about' is an insertion indicator.
'more' with its last letter taken off is 'mor'.
'a'+'tad'='atad'
'atad' placed into 'mor' is 'MATADOR'.
'that' acts as a link.
(Other definitions for matador that I've seen before include "Spanish performer" , "One in the ring" , "Performer in the Ring" , "paid killer" , "fighter in the ring?" .)
