yeah, I am not sure I believe this part:
I find it very hard to believe that the MSP and DNR are that coordinated. "Purchasing a license" also consists of going into compass and paying money, and it is virtually instant. I highly doubt they can complete background checks that quickly. Getting a harvest confirmation is also instant. I'd bet that if it actually does happen, people are popping up on the MSP radar for other reasons.
That said, any information you give the government can be used against you and you should assume that it will be. The government is not and never shall be your friend.
It has happened on more than one occasion.
