isn't Hitchcock, yet Russo-ISC was based off of Horatio Caine, as already mentioned upthread. The titles are obviously Hitchcock allusions, but there was a clear Fugitive reference too, jumping out of the drainpipe to go on the run.
I'm not seeing any obvious overall parallel in this episode with The Man Who Knew Too Much,
beyond the title; where was the famous cymbal clash to cover an assassination?
It's a hybrid.
