Wanting& Doing is another matter! Another point to consider if i may, if a bullet hits you in the back it wont always exit via the opposite site, it has to go through muscle tissue, bones&vital organs often being deflected distorting the bullet & causing a massive damage on its way out. I also put the case , if its a conspiracy it was a badly executed one, i for one would want a heck of amount of money & a foolproof way of getting away with it before i would attempt this sort of venture, no evidence that i know of has been put forward .
