I haven't done an in depth study, but I have kept my ears open ever since Tawana Brawley. (Plenty of these type stories on the local news down here in Atlanta. Black family moves in....some weeks later, N-word sprayed on garage door)
So far it has been 100% (not "most", not "just about") but 100%, every single time, without exception, it has been a fake perpetrated by the "victim".
If that Lincoln, Nebraska case doesn't come back as phony, I'll eat my hat and adjust my number to 98%.
I would bet by now even most bleeding-heart libs groan every time they read about these “hate crimes.” But since libs are the most easily duped and gullible (and ignorant) people in the universe, a core contingent will still be set up by the hoaxers only to served a hot plate of crow at the end of the story. It seems just as all political vandalism and attempts to shut down free speech come from the left, all hate crime hoaxes come from the left as well.
