Shockingly, bold ULEZ militants say they'll do this to enforcement cameras (8)
I believe the answer is:
bulldoze
'militants say they'll do this to enforcement cameras' is the definition.
The definition suggests a singular noun but the answer is not.
'shockingly bold ulez' is the wordplay.
'shockingly' indicates an anagram.
'bold'+'ulez'='boldulez'
'boldulez' is an anagram of 'BULLDOZE'.
Can you help me to learn more?
(Other definitions for bulldoze that I've seen before include "Railroad" , "Destroy" , "Raze to the ground" , "Force through (against all opposition)" , "Knock flat" .)
