If only!
When Trump is here, his exposure is very carefully limited and he's mostly cosseted away on his property behind several layers of security and police. His "walking the course" ritual isn't him striding over the lonely, empty dunes - He's got so many people round him that the only way to identify him is when the wind off the North Sea catches his combover and sends it vertical - above everyone else!
The nearest I can think of to anyone getting close enough to heckle was when he presented to the Holyrood committee on windfarms.
And arrived with an uncharacteristically small security detail.
That's his local head of security going for the guy with the balloon.
