Boston Marathon bombing suspect hasn't been read his Miranda warning

So the second Boston Marathon bombing suspect has been arrested but hasn't been read his Miranda rights. 

The US then - behaving precisely how Russia would behave (and be roundly criticised for) without a second thought.

There is also now increased talk of trying him as an enemy combatant (with no attorney etc.) instead of with a criminal trial. This is a 19-year old US citizen we're talking about.

Interestingly, the Guardian wrote a piece before the arrest with a tone that suggested there was no way this was going to happen:

Most people take the supreme court decision in Miranda v Arizona (1966) to be the final word on whether arrestees must be informed of their right to an attorney and to remain silent. They must, the justices decided.

According to the Huffington post, Miranda rights can be waived in the following situation:

The public safety exception permits law enforcement officials to engage in a limited and focused unwarned interrogation of a suspect and allows the government to introduce the statement as evidence in court. The public safety exception is triggered when police officers have an objectively reasonable need to protect the police or the public from immediate danger.

Objectively reasonable? LOL.

The exception is bullshit anyway, but how is anyone in objective immediate danger when one suspect is dead and the other is under arrest?

Laws are designed to deal with people who have committed the worst crimes, not be suspended for them.
