This article is ridiculous. It starts with the assertion "Dzhokhar Tsarnaev will not hear his Miranda rights before the FBI questions him Friday night." How do we or the author know this, is he assuming this is common practice, has FBI mentioned that they won't read him Miranda?
Second, I was expecting him to mention a case where the police or FBI didn't read the rights to what turned out to be a non-threat/wrong accusation, etc. At least in all the cases mentioned this is not the case, the person presented a clear and present danger.
