Prisoner Release Nov 1

Some people watch movies for a a large part of thier TV day, but I watch Congressional testimony.  In the Immigration hearings on Tuesday there was in interesting exchange with the Director of Homeland Security as to whether he knew that changes in the sentencing guidelines would cause the release of 10,000 prisoners, many of them illegal aliens, on the 1st of November.  He said he was aware of it and was working with the Justice Department (that would be the same people who changed the sentencing guidelines retroactively) to determine what should be done to make disposition of these people.  This was the first I had heard about this.  It was one thing for the President to release 46 prisoners before their sentences were up, but it quite another to release 10,000.  What idiot proposed that kind of thing?
