Why wasn't Malvo deported, once INS determined last year that he was an illegal alien?

Why didn't the feds circulate his fingerprints to Alabama law enforcement?

Why were the police profiling the sniper as a white man, when only 55% of US snipers are white? According to the Wash Post, the DC sniper car was spotted at least 10 times in the search, but it apparently didn't match the profile. It seems to me that an unemployed man named Muhammad driving a old beat-up Chevy Caprice with an illegal alien should have matched the profile.

"We were looking for a white van with white people, and we ended up with a blue car with black people," said D.C. Police Chief Charles H. Ramsey. ...

Another witness, a restaurant employee in the area, said in an interview that he also saw a Caprice slowly driving away but did not volunteer the information to police until after the suspects were arrested, because he assumed agents were looking for a white van. [Wash Post]

I don't want to blame law enforcement, because some of them did a very good job. But when we are at war with foreign Mohammedan terrorist, you would think that federal policy would focus on the people who are causing the most trouble.
