And then if you stuck around to see the gory details as he got turned over, he had blood all over his face.
It was probably reported in all the papers that Sherlock threw himself off a roof at Bart's Hospital. If you were walking past the Hospital at the time, you would definitely put two and two together.
The whole nobody noticed someone falling off a roof in London during the day is more far fetched then Moriarty Scooby Doo masks.
