2. The State Police shall provide its response to the requesting dealer during the dealer's request, or by return call without delay. If the criminal history record information check indicates the prospective purchaser or transferee has a disqualifying criminal record or has been acquitted by reason of insanity and committed to the custody of the Commissioner of Behavioral Health and Developmental Services, the State Police shall have until the end of the dealer's next business day to advise the dealer if its records indicate the buyer or transferee is prohibited from possessing or transporting a firearm by state or federal law. If not so advised by the end of the dealer's next business day, a dealer who has fulfilled the requirements of subdivision 1 of this subsection may immediately complete the sale or transfer and shall not be deemed in violation of this section with respect to such sale or transfer. In case of electronic failure or other circumstances beyond the control of the State Police, the dealer shall be advised immediately of the reason for such delay and be given an estimate of the length of such delay. After such notification, the State Police shall, as soon as possible but in no event later than the end of the dealer's next business day, inform the requesting dealer if its records indicate the buyer or transferee is prohibited from possessing or transporting a firearm by state or federal law. A dealer who fulfills the requirements of subdivision 1 of this subsection and is told by the State Police that a response will not be available by the end of the dealer's next business day may immediately complete the sale or transfer and shall not be deemed in violation of this section with respect to such sale or transfer.
