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

'prison' is the definition.
(I know that Panopticon is a type of prison)

'criminal can't poop in' is the wordplay.
'criminal' indicates anagramming the letters.
'cant'+'poop'+'in'='cantpoopin'
'cantpoopin' anagrammed gives 'PANOPTICON'.

'all-seeing' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
