This is a scary piece of news. Really sorry to hear about it.
I found this excerpt from a MD shooting forum that pertains to your situation.

It looks like you are not the only one getting incorrect info from MSP.
Quite possibly, the first trooper you talked to took notes and since the push is now on to "DO SOMETHING" about illegal guns,you where chosen!
God Bless!
