I have to agree the Boston PD acted rationally and with the exception of not reading him his Miranda (somebody needs to be FIRED for screwing that up) they acted VERY professionally.
Hey, I haven't visited slashdot in years, but I thought I'd see what everyone's saying about the marathon bombings since I work and live in Boston. I just have to stop you right here. No, I don't have any specific information as to who first cuffed the suspect (Watertown PD, Boston PD, state police, FBI... etc) and I don't have any specific information as to his medical condition past what has been released about his non-communicative state. But I really don't think Boston PD had anything to do with deciding whether or not to read him his Miranda rights, nor do I think he was in any state to receive or understand those rights. He had been bleeding out since the shootout (for over 12 hours) and had just been in another shootout where some sort of flash-bang grenade was thrown at him. The first thing they did was bring him to a hospital, not a police station. If a suspect can't talk, you can't really interrogate them and the right to have a lawyer present and the right to remain silent aren't physically necessary. The time to read him his rights would be after he regained consciousness/ability to communicate. And by then I would expect that the feds would be the ones in charge of how he's handled. I really don't think that local cops were calling the shots at that point. I think it was a little less, "Hey Frank, what do you think, should I read him his rights or just give him a few punches?", and a little more, "US Attorney Ortiz, what is your legal opinion on whether we should interrogate the suspect as to possible on-going public safety risks prior to informing him of his Miranda rights?".
