Some of it is in my brief. Some of it pertains to who your PAL references can be. I don't think they should be immediate family members or close friends. Passport requirements are stricter, but you can't shoot somebody with a passport.
I've mentioned the stage A failure override and the system data, and I've also read, for example—although it's not confirmed and it's been in newspaper reports—that due to resource levels, references are rarely contacted, if ever. I don't know what sort of validation ever goes on to ensure they're appropriate to be providing a reference for somebody applying for a gun, and so on. There are many areas I could touch on.
