In this editorial piece by the New York Times, they take a hard look into the Texas school system and it's lack of structure for disabled students.  According to the piece, Texas has the highest amount of disabled students than any school system but the least amount of education for those students.  The article goes on to state that teacher's have very little education about the issues facing disabled students and because of this, many of these kids are getting turned out onto the street. 
When they act out many end up in jails over-populated with juvenile delinquents who really need help that they are entitled to under federal law.
