Did Davis witnesses commit perjury?

There have been several articles concerning the fact that Troy Davis claims innocence in the death of a Savannah police officer in 1989. At the time, after listening to numerous witnesses, the jury found him guilty. Recently, several of the witnesses have seen fit to change their testimony.

I do not claim to know whether or not he was guilty, and that is not the point of this letter. My question is why it took 18 years for these people to realize that their testimony was false. Were the witnesses sworn before taking the stand? If not, why not? If so, why do I not read the word "perjury" in these articles?

The man has spent many years waiting for his execution because of their testimony. If he is innocent, what are we to do about the people who caused this? Even if he is still found guilty, what are we going to do with the admitted perjurers?
