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

'for helping illegal activity' is the definition.
I can't tell whether this defines the answer.

'a tablet reconfigured' is the wordplay.
'reconfigured' indicates anagramming the letters.
'tablet' is an anagram of 'bettal'.
'a'+'bettal'='ABETTAL'
