Having been both a Police Officer and a helicopter pilot....knowing the way the murder of an Officer affects his fellows....much less the murder of four of his fellows....when told to shove off....SHOVE OFF!
The Police would have been helpful by specifying exactly where they wanted the KING Chopper to place itself....even if that was back at the hangar.
The news folks could be a very great help in this investigation and the Police should find a way to work with them re the News folks need to report on this tragic event.
I would trade full coverage of the investigation provided the News people promised to NOT cover the arrest. That would simplify the resulting legal mess post arrest.....especially if there were no need for pre-trial incarceration, arraignment, trial, or imprisonment for the fellow that did this.
