I did not say that the 'exact count' was proof of an investigation - I pointed out that the initial reports that came in stated that survivors and others were being interrogated/interviewed to determine what happened - i.e investigation.
Details of operations along the border need to be provided since the border, as the West itself likes to say, is poorly demarcated and insurgents move back and forth along it, which might result in troops being mistaken for insurgents massing to carry out attacks.
The same reason the US/NATO uses to carry out attacks inside Pakistan - the area has been used by terrorists to stage attacks into Pakistan and Pakistani forces might have (since fire by Pakistani forces first has not yet been established) fired thinking they were attacking terrorists moving across the border, or they might have thought the 'terrorists' were already on the Pakistani side of the border, since it was night and visibility was poor.
An alternate possibility - NATO/Afghan soldiers were sheltering/protecting terrorists launching attacks into Pakistan, came under Pakistani fire because they were caught, and resorted to CAS to save themselves and the terrorists.
NATO conducts operations along the border quite often and their air support is probably in the air non-stop - tracking fighter jets in the air would not provide any indication of a potential attack on a Pakistani border post. Low flying helicopters would be hard to detect on radar in that terrain.
Arguing against the 'status quo' is a necessary part of changing societal opinion - whether done by this government or the next.
Hey, the US was claiming the ISI went all the way to Kabul to carry out some attacks .... compared to that nonsense, this makes sense - US/Afghan special forces acting in concert with terrorists planning to attack Pakistan trying to sneak across the border (or perhaps even attack the check posts pretending to be militants) got caught and came under fire and resorted to CAS to save themselves.
