Hello. First post. I'm writing a book about a fictional city being run by an occupational force in the near future. My protagonists wish to expel them from the city not by killing them, but by getting the docile population to stand up to them. I have an idea about a large operation the protagonists wish to execute, by infiltrating an area that's off limits in order to extract evidence of a certain secret that would get the population outraged, in order to destabilize the regime. The problem is, I can't come up with a secret good enough that would explain why the heroes are going to such lengths to get it. I guess I eventually will come up with one, but I want to hear ideas that might be better than mine, so I can get there sooner. If anyone can think of something, I'd love to hear it. Thanks.
