We have not seen the last of the charges to come, and there is likely some criminal action that won't be prosecuted. It is important to remember that a responsible prosecutor will only bring charges that he or she thinks will end in a conviction. Sometimes, they may know what is very likely to have occurred, but do not have sufficient evidence to legally "connect the dots" to meet the burden of proving beyond a reasonable doubt. A prosecutor, like the BISD trustees, is a steward of taxpayer money and should not be wasteful in his or her endeavors.
But to think that all of the BISD corruption/illegal activities has already been exposed is naive at best in my opinion.
