Not off topic: You changed 3 negotiator. You were all speaking at the same time.. Neither you understood my demand, nor I understood what you were talking. I have full 20 minutes POV that even in the first minutes you were rushing the roleplay. POV is full of the "Be fast", "Finish the event", "I don't have time", "Lets end this and leave". You don't care and fear about hostage's life, you don't care about to keep the continuation of the roleplay, which is a rulebreak. I may have a mistake in my words and sentences. But if you cannot listen each other you cannot understand and help people do correct their mistakes. The roleplay isn't a movie script you should follow and make it happen in 10 mins. It changes and evolves every time. If needed it must be done for 1 hour. I'm not intended to do 1 hour roleplay. But you're definitely intended to do 1 minute roleplay.
BTW: I asked an admin before If I can give a demand to LEOs to leave. And he said "Yes, after you release the hostage". And that was the whole situation of what I was planning. But when they started to interrupt me, the negotiation became a mess.
