Yes.
By omission. You are implying something that is false.
Why did Sarah miss the caribou so many times with her fathers gun?
And a more pertinent question. Why is it so easy to determine the intelligence (or lack thereof) of her detractors. This is not a trick question.
Her father tripped and probably knocked the scope off sight. Happens but most hunters would have test fired to see if sighting still on. Like others I feel the varmit cartridge was a bit light for carabou and the one she used for one shot kill looked to be a bigger caliber, at least 7mm.
