Well, about the explosives--all the police knew was that explosives had been thrown at them during the chase. It was a logical assumption that the second suspect might have more. A reasonable precaution, if you will. He might have not had them, but I can see how law enforcement would continue to operate on the assumption that he might have more. Better safe than sorry, and all that sort of thing. I grant you, there's a lot of misinformation flung about in an emergency, and I don't think the rabid news media helps.
I avoided tv for most of the week, but I did watch the final hours of the manhunt--the local stations were covering it without stopping for commercials. At one point, a guy in the newsroom was asking a reporter on the street where he was, so that the newsroom people could tell him how to get closer to the scene of the action. And the guy on the street stopped them--"I'm not getting any closer. I'm not moving. The police won't let me and I don't want to." That's what I mean by rabid news media--getting too close to flying bullets.
And I'm only talking about "police state" here as it applies to conversations people are having about how Boston looked on Friday. Just because the streets were empty does not, to me, signal a police state. I used to walk to church every Sunday through the Common and it was just as deserted, but that's to be expected at 7 am on a Sunday.
Am I concerned about how our rights have been trodden upon since 9/11? Yes. Do I think this one incident in Boston is an example of that? No, as regards the general public.
Am I concerned that the suspect in custody hasn't apparently been read his Miranda rights and may not be read them? Yes.
Do I have an answer to balancing freedom from terrorism and freedom of personal rights? No. I wish I did.
