Bias could play a key role on reporting this story depending on the perspective of the author.
An author that is pro intervention and support the war effort - commonly known a a hawk - could report the incident as something isolated that does not reflect the true competence of the army neither the overall sucess of the war effort.
An anti-war author, on the other hand, could report the same fact as one in a line of horrible accidents that demonstrate how wrong and futile is to engage in modern warfare and how lives are considered to be disposable by the leads of the army and government.
Personally, I am biased against the so called hawk and their choice for "clean and effective" use of airstrikes and drones, I don't think they are truly committed in preserving the lives of the innocents neither the lives of the soldiers if some extra deaths lead to a desirable accomplishment of their goals.
The quote below clearly shows that there is a lot yet to be uncovered regarding the incident.
"A mother of one of the soldiers killed in the attack has repeatedly spoken with the press, making known her intentions to launch a full investigation of the fatal error.
