Not picking a fight with you . . . but you would suggest that it would be better to pick them up right away, even if it jeopardizes the case against them?
If they were somehow involved in the planning and execution of the massacre at Sandy Hook, yes, they should be picked up now. I am guessing that the case against them would be rather ironclad if true. I would hate to think that they might have the opportunity to pull off another massacre.
If the people they say are tagentially involved in the event, then yes, it might be prudent to delay any arrests.
If the delay in the report is political however, how would we know? We just get manuvered into the corner for the sake of the children.
