Frankly I am still surprised that the FBI has not fully taken over the investigation at this point. You now have 6 counties, plus the District of Columbia involved in this investigation. All for all the cheery talk about cooperation between agencies, there are just as many stories of information being lost or not getting across.
But now that the sniper(s) is supposedly talking to police it might make sense to keep it under the control of the Montgomery County PD for that purpose alone.
And just my 2 cents... I think any police official would be overwhelmed by a case like this. I think it is unfair to characterize Chief Moose in that manner.
