An unfortunate consequence of fame is that celebrities are sometimes forced to take counter surveillance matters into their own hands.
As it’s difficult for a celebrity to accept new people into their inner circle without knowing their motives, pre-emptive measures can be used to vet outsiders. The unfortunate consequence of this is the application of questionable methods by shady security forces. Celebrities don’t have their own Secret Service detail so they end up relying upon their peers to perform investigations of outsiders entering their fold. This can be disastrous all around, particularly when there exists political and cultural disparities amongst involved parties. Speaking from experience.
