Because when the investigation first started, these three lied to investigators to help Ramos and Compean cover up the shooting. They could have each been tried for some of the same crimes Compean and Ramos were convicted of, covering up and hindering an investigation. But since they were not the shooters, they were given immunity from prosecution in exchange for them testifying about the events of the day, testimony that included them confessing that they had lied to the investigators at first and had not followed procedure about reporting a shooting. One of them even helped Compean destroy the evidence. They were fired for their lies covering up the shooting. NOT for lying in the trial. Either there are a lot of ignorant people on the pro-pardon side, or they are deliberately mischaracterizing the firings in order to confuse people into supporting their side.
Liars, liars, liars, who is lying? Who do you believe? All have been caught in a lie somewhere. But who is the biggest liar of them all? Believing the drug dealer is buying into a lie first off--I'm telling you FROM PERSONAL EXPERIENCE--they don't know how to tell the truth. They are so divorced from the truth it's pathetic.
Number two, the big lie that we had a unanimous jury hasn't even begun to be addressed, so conveniently forgotten.
And the "crime"? What a joke
