Really, though, it's an apropos word that should go into the language. "Pre", something existing beforehand, "ju", a shortening of the Latin "jus", right or law, and root of words like justice, judgment, and "-cide", a killing. A killing because of a pre-existing judgment, or a killing based on a prejudice.
I think it's a good word to replace "hate crimes", in cases where the crime is a killing or attempted killing.
