Criminal Aliens

Homeland Security Secratary Janet Napolitano stated that if you are a criminal and your are not entitled to be in the U.S. then she wants you out of the country. She wants to take all of what she calls "Criminal Aliens" off the streets so that you can get "the most bang for your buck". When reporters talked to her she said "That sounds very simple, but it's historiclly not been done." I just happen to disagree
When the New World was being colonized Queen Elizabeth did something that I believe made a big difference in Europe and in our new forming country. She decided that they had too many criminals on the streets and too many outcasts that were not benefiting in her society. So she did what Napolitano says has never been done before. She took all the criminals and outcasts and she shipped them over to a New World where they could start new lives for themselves and learn how to work for what they needed and wanted in life.
I'm not trying to say that she is wrong for what she is trying to do. All I am saying is that I believe something to the manner of what she is trying to achieve has already been done before and very successfully at that. Now why can't we just ship all of our criminals to some unused land where they can fend for themselves? Is it inhumane? Well I'm not going to pretend that I know exactly what we should do and I'm not 100% that it would be the best thing to do. But I honestly think that if we were to clean our streets up of all the people that are only hurting our society as a whole and ship them to let's say....Canada I believe our country would benefit greatly.
