Criminal carrier has nothing to hide (4)

I believe the answer is:

hood

I'm a little stuck... Click here to teach me more about this clue!

'criminal' is the definition.
(I know that hood is a type of criminal)

'carrier has nothing to hide' is the wordplay.
'carrier has' becomes 'hod' (I am not sure about this - if you are sure you should believe this answer much more).
'nothing' becomes 'O' (O resembles 0).
'to hide' means one lot of letters goes inside another (some letters hide inside others).
'hod' placed around 'o' is 'HOOD'.

Can you help me to learn more?

(Other definitions for hood that I've seen before include "Bronx district" , "Cover - American gangster - Robin?" , "See 8" , "Bonnet (US) - gangster (US)" , "Protective cover - violent criminal (slang)" .)
