Jоhn, а bаnk teller, is аccused оf embezzling frоm the bank where he works by making dummy withdrawals from customer accounts and pocketing the cash. At his trial in Alaska state court, the prosecutor calls the records custodian of the bank and shows them copies of several pages from a ledger on which the dummy payments have been highlighted. The bank's records custodian identifies the copies as true and correct copies of the bank's ledger and testifies that the ledger is one that is routinely kept by the bank, is updated at the end of each business day, and is kept in a locked vault with access limited to the bank manager and the records custodian.The prosecutor then attempts to introduce the ledger into evidence. On which of these grounds could John's attorney make a valid objection to admission of the ledger?
