I have a personal friend who knows the doc that treated Kerry for the "wound" that he fanagled getting a purple heart for.
It was self inflicted, the oaf shot a grenade out of a grenade launcher at shoreline rocks and a tiny piece stuck in his skin. He did not pull the sliver out himself, but rather sought do document his "war wound" by gettng the doc to flick it out and slap a barely needed bandaid on it.
I was an M203 grenadier and can say that it could easily have happened that way. Those rounds arm themselves at a short distance out of the tube, and the contents can injure the grenadier. IIRC, the old M79 worked about the same way.
Here's what Snopes says about Vince Foster's alleged Swan Song letter:
"White House deputy counsel Vince Foster committed suicide on the night of 20 July 1993 by shooting himself once in the head, a day after he contacted his doctor about his depression. A note in the form of a draft resignation letter was found in the bottom of his briefcase a week after his death."
It was a pathetic effort, the letter was torn into scraps, suddenly appeared in his briefcase several days after his death, and once again, Snopes is full of baloney.
