I've often thought it's only a matter of time before things like this happen with dangerous game and TV, with all the extra people it takes to film a hunt.
I have seen shows where the PH was the one to tell the hunter when it is time to chamber a round. I assume to prevent accidental discharges like this. Maybe the PH gave the OK given the tight quarters.
"The budget should be balanced, the Treasury should be refilled, public debt should be reduced, the arrogance of officialdom should be tempered and controlled, and the assistance to foreign lands should be curtailed lest Rome become bankrupt.
People must again learn to work, instead of living on public assistance." - Cicero , 55 BC
