Seeking "intelligence" agency PPT theme

Need help locating a PowerPoint template that I can use for teaching (briefing) law enforcement and security managers on sensitive matters pertaining to major events. I am thinking a dark background with formal looking font, perhaps, a subdued color that will still stand out on a large projection screen. Grays, blacks, etc. I only need images and text, no head shots, no charts or graphs, nothing related to selling a product or business, etc.
