It is, 100%. Surveillance goes on constantly in Sri Lanka of families of victims. It's constant. It doesn't matter if an individual has left Sri Lanka or is still there. The fact that somebody has made a complaint means their entire family is surveilled.

The surveillance can be your simple police officer at the end of the street surveilling you. They are not just victims of other human rights violations but also of enforced disappearances.
