Getty Images  has announced that beginning Oct. 1  the agency will no longer accept photos of models' body shapes that have been retouched.

Businessman Chris Kennedy  jumped in with  his  take: âThatâs why we have a divided government â  he  said. âFor gosh sakes  if weâre not going to call out other parts of government â if you donât see your role as governor to call out a mayor whoâs not representing the people of a certain city  if youâre not willing to call out an assessor whoâs violating the 1964 Civil Rights Act â if you donât think thatâs the proper role of government  you should go read the Constitution ...
Well  yes  Iâm all for calling politicians to account â pointing out their failings and demanding they do better. And while I understand that constructive criticism and attempts at engagement and compromise arenât politically fashionable  I donât think  Kennedy  set the table for long-term success  should  he  be elected  with  his  over-the-top accusation earlier this month that Mayor Rahm Emanuel is leading a âstrategic gentrification planâ to drive African-Americans and other minorities out of the city.
Iâd say the same thing about  Kennedy âs repeated claims  one example seen above  that successful property-tax appeals result in less money for our schools.
Thatâs not how property taxes work. Schools set an overall levy  and that amount is divvied up among all the property taxpayers in the district. When your tax bill goes down after an appeal  everyone elseâs goes up fractionally to compensate. Candidate Daniel Biss  a state senator from Evanston  explained this clearly to  Kennedy  during a similar session Wednesday before the Chicago Sun-Times Editorial Board.
