How much research and single-minded effort did it take for Dan Rodricks to find one illegal alien who has now (against enormous odds) become a Hopkins neurosurgeon ("'Illegal' immigrants and the next economy?" May 15)?

Has Mr. Rodricks conveniently forgotten about Adan Canela and Policarpio Perez (both illegal aliens) who were charged with the 2006 brutal murders of three Mexican children?

Has he dismissed the multiple arrests of Juan Gonzales (an illegal alien) for child rape in 2005, 2008 and 2010?

Does he not remember the 2007 Bethesda attack victim, Mary Haverstein? The alleged attacker was an illegal alien.

And let us not forget the Montgomery County murder of Joe Lombardo in 2009 and his illegal alien assailant, Jose Antonio Pais.

Kudos to Dr. Alfredo Quinones-Hinojosa, the neurosurgeon at Johns Hopkins. His efforts and struggles are to be commended. However, I believe that it is a callous insult to "Dr. Q" (and any other neurosurgeon, for that matter) to simply bundle all illegal aliens into this doctor's respected echelon of success.
