I doubt that Pat Tillman’s family will be sending congratulations.
Friendly fire incidents are always emotional for the grieving family. Unofficially the military has always tried to put the best face on it even if it meant being somewhat loose with the facts.
Nothing that I know of has been reported to indicate anything other than an accident. If it was an accident I’m not sure what Tillman’s family’s concern is.
If the family has other information pointing to murder by another American or Allied soldier then they have every right to pursue it. I’m not a McChrystal fan. I’ll say that right up front. So, if he tried to sweep something under the rug he should be called on it. Hell, it may have been McChrystal’s ridiculous ROE that got Tilman killed for all I know.
IMHO, McChrystal represents everything bad about current senior military leadership.
