Negotiation/Negotiator type Callouts:
eg: You have to respond to a Hostage situation ( like what Exiled suggested ), whereby you have : multiple choice : options as to 'how' you are going to handle the situation, or rather diffuse the situation in a peaceful manner. I'd assume some sort of GUI with multiple choice lines, alongside a slider bar/ as to the perps aggression level. Similar to what was seen in, I believe it to be your Callouts+ mod for : suicidle suspects. ( I hope that made sense )
Would make for some fun callouts.
I would'nt know how hard/long that would take to code. Or if even possible
