I posted a different reply because I had never heard of getting permission from the local police to purchase a gun. Usually you only need their permission for a CCW permit. My understanding is that it was a matter of the gun dealer running your info against the NCIC gun clearance database. Apparently in Minnesota you need to have permission from the local police department before going to the gun dealer. I have never heard of that. Thus, I stand corrected for anyone who read my previous post in the 10 minutes it was up.
I should mention that the local requirement applies to assault type weapons and hand guns. There is no such requirement for a standard hunting rifle.
