Regarding the Aug. 23 news article “Sanders, Grijalva ask DHS to end use of privately operated detention centers”:

Government contracts with for-profit, private companies use our tax dollars on unneeded and unsafe immigration detention centers such as those in Dilley and Karnes, Tex., which lock up women and children coming to our country seeking safety and protection. There are a number of proven alternatives to immigration detention that are more humane, safer and more cost-effective. And with The Post’s recent in-depth look at the deal behind the facility in Dilley, “Windfall deal for asylum facility” [front page, Aug. 15], it is clear these alternatives are needed more than ever.

We must end the use of for-profit corporations to run our government’s immigration detention facilities and stop locking up women and children. If the Justice Department can open its eyes to the problem, the Department of Homeland Security can surely do the same.
