Yes, the real Omar jumped out the window and survived.... and the REAL Omar is still alive. Meanwhile, the TV version was killed in the most unceremoniously way which is more realistic than any death from Breaking Bad.
at the realism angle. Realism has never been a yardstick for the quality of fiction, so toss that argument out the window.
I said, by the creator's own admission, "The Wire" wasn't meant to be strictly realistic. IE, Omar jumping out the window (which happened), then going on a killing spree like a Terminator (which obviously never happened). Omar was meant to be larger than life, "the establishment" was meant to be a stand-in for vengeful/indifferent Gods, etc.
Like I said, a Greek tragedy.
