Thumbs Up: To Supt. Linus Wright for his public commitment to clean up the school district. Recent revelations of financial impropriety in the DISD administration only touch the surface of a managerial system fraught with incompetence, lack of accountability, and evasions of responsibility.

Not surprising, considering that all but one of the current members were on the board when the whole mess started.
