Eh, I've never much cared for that quote or the common interpretation of it. People take it as though the problem is the surveillance. But it's the last part which tells you what's up: "I'll find a way to hang him". The speaker is telling you what they're going to do - everything else is a formality. Your problem began well before they had a sentence, and wouldn't end if they didn't have one.
