Thanks was just looking for something like thatThis article / opinion piece from The Los Angeles Times might help put it in perspective. It discusses the public safety exception which was put into play before any questioning began.

"On Friday, the U.S. attorney in Boston said the Justice Department was invoking a "public safety exception" to the Miranda rule that in most cases requires police to advise suspects in custody of their right to remain silent and their right to an attorney. Under the exception, announced in a 1984 Supreme Court decision, police may forgo reading a suspect his rights in the interests of public safety and if the suspect then makes an incriminating statement, it can be used at trial."
More, of course...
Key words being "public safety". There is a time limit as well.
Yeah you know the feds were not going to blow this by letting him say things they can't use later. It's not their first rodeo
