First of all, you have to drop this 'government offices are closed on Sunday' bit. Whenever there's a major investigation going on like the one into the bombing and bombers, there's at least as many pencil neck geeks in the offices as there are agents in the field - including the mucky-mucks who make decisions like when to file charges.<quoted text>
I'd hafta say the DOJ errored at least twice on this.
1) Gov't offices are closed on Sunday, and waiting until Monday AM
would've given the FBI a chance to glean additional info.
2) Communication. The FBI is PART of the DOJ, and as such it would've been "cleaner" to at least tell the interrogators that people were on their way (on a Sunday) to mirandize Dz-Jokar.
The magistrate appeared unannounced, where perhaps X more questions
may have been answered while she was enroute.
I'm aware there is no set number of hrs to question someone under
PSE, but apparently SOP is 48.
The Department of Justice and the Department of Homeland Security were at 'General Quarters' that weekend, and some of them probably STILL are.
Second, the filing of formal charges requires certain procedures, which includes a reminder by the judge (in Federal court, usually a magistrate) of the rights of the accused.
Third, neither you nor I know anything about the communication between DOJ and the agents in the field, or between the supervisors and the field agents on site, other than some press reports that some of the agents expressed surprise at the timing. We don't know if that was just typical top-down FBI management or a deliberate decision by the supervisors to withhold the decision until the last minute for tactical reasons.
You want to question the timing, fine - I've got questions about the timing, and not knowing if anything was done wrong is different from swearing that everything was done right. The thing is, since I don't know (and doubt I ever will know) the specifics of the investigation in that hospital room, I probably won't be able to get those answers.
