I have no idea whether OJ did it or not. But the prosecution made such a mess of the case that I think the jury did exactly the right thing in finding him 'not guilty'.
Vince Bugliosi, wrote an excellent book on the subject in which he poitns out numerous errors on the part of a lot of people: Gil Garcetti, Judge Ito, The prosecutors, etc. etc. A reading of this book clears up any confusion on OJ's guilt or innocence. He did it, no doubt about it.
As for the jury, they were F----n idiots who did not have the brains of turnips. The evidence was there, but presented in a terrible fashion.
If Ito had any balls he would have been justified in throwing out the verdict and directing a guilty one. But he was too much of a lame ass.
