Someone, so this is a is a family fight. BTW, I never said wrote all frum Jews are customs evaders only that this has happened and suggested that as a reason for extra alertness.
As for trhe conversation tou reported, to whom are you referring?There is a law against improproperly taking advantage of a public position. The offense is called “hafarat imunim” (betraying trust). Maybe if your cousin could arrange for the Proklitut to ask this person a few questions it would help.
