There are people that were able to ‘suicide’ themselves by shooting themselves in the head twice or killing themselves with a nail gun.
By these ‘standards’ all is possible.
Call it conspiracy theory, coincidence or just bad luck, but any time someone is in a position to bring down Hillary Clinton by testifying they wind up dead. In fact, there’s a long history of Clinton-related body counts, with scores of people dying under mysterious circumstances.
Perhaps the most notable is Vince Foster. Foster was a partner at Clinton’s law firm and knew the inner workings of the Clinton Machine. Police ruled that death a suicide, though it is often noted that Foster may have been suicided.
