Why does the govt. not catch tax evaders who withdraw black money using their atm debit cards of non-indian banks? i mean, the atm stores card numbers, and the govt can monitor all atm transactions over the year and make a list of all card numbers(especially those belonging to non-indian banks) who withdrew a total of say 20 lakhs or more over the year...because those cards likely belong to the richest of the richest, who could possibly be withdrawing black money stored in hidden a/cs... does the govt do this? why not?
