Confrontation

Don't move! From this moment and until we clarify all the circumstances, you are under arrest. What circumstances? Don't be smart!
Oh, you don't know? Don't know nothing, didn't see nothing? OK, I will remind you about a couple of facts. Last night you were seen with Harpoon the Brassbound, you were discussing something with him. Ten minutes after your conversation, Harpoon attacked Commander Shorr and sent him to the Purgatory. What do you have to say for yourself?
You say that you weren't here last night? But you could've used the lift... What do you mean, it's broken?! Can someone confirm that? Crow the Riverborn, Kibal Chikhun and Cha Pie-Pie himself? Yeah, well, it does seem that you have a strong alibi. Then who was seen with the murderer last night?
You know what, let's have a confrontation. We'll question the both of you, and see what lies each of you tells.

Harpoon is in that tent. Come on, it's time for the interrogation.

What does that mean? Who gave you the right to execute the suspect before a court verdict?
