The buggy wasn’t driven by Trump, but is thought to be his “getaway vehicle” should anyone open fire on the course. The black, obviously armored vehicle followed Trump around as he played golf, with many experts noting that it bore similarities to “The Beast” — Trump’s protective vehicle stateside.
Going by the article, it’s just a freak coincidence.
EDIT: To be clear, I haven’t heard about that incident prior to this, haven’t ever read about Carter-era stuff, so I only know what’s in that article. shrugs Maybe the guy changed his name prior to the incident, maybe they only reported claimed names, dunno.
