This is all conjecture on my part, but I have experience (Been right once or twice with it).
So reports/claims are the drone strike that destroyed the VBIED actually killed a guy that worked for an American NGO and a former DOD contractor (Both Afghans) and their families. Not saying this is true but wouldn't surprise me if it was, especially if it was the Taliban providing the intel. Seen stupid shit like this done before in another theater. (a lack of a secondary explosion on the vehicle got my suspicions going).
