illegal immigrants in prisons

The u.s likes to make claims of how illegal immigrants commit a lot of crime and make statements that federal and state prisons are mainly made up of illegal immigrants. the truth is that less than 1/3 of inmates are non citizens. in the last few years the non citizen inmate rate has decreased to less than 20% in federal and 6%in state. i think that illegal immigrants are just the escape goat . i don't think that ,a small percentage of illegal immigrants that come over should give a reputation for all the others. If the u.s doesn't want to spend money for illegal immigrants in prison why don't they deport them saving money. i think that people believe anything they are told and unaware of the statistics. http://www.nytimes.com/2007/05/30/business/30leonside.html
