I don't think you can stop anyone with bad intentions of getting one with any licence or not I know some rules in the COVID did go lax and there was errors there as a large backlog and police was overstretched with other matters you look at the one lad that planned to kill his family he had a licence and meets the dealer in the carpark by his mom's flat or the moors murderer she was going to a gun club and the instructor noticed she had a very short fuse
