The average cop does not, honestly the only people that are technically allowed to see a stamp is the IRS or the ATF since the tax stamp itself is a form of tax return, its confidential material...
Technically the law states it has to be avaliable, nothing says you have to have the stamp or copy on your person, you can always retrieve it or a copy at the ATF's request. Local LEO's have no right to view said material.
That said, if you refure to show a stamp you may be arrested and spend some time in a cell until they figure out your legal. You will be released but its a hassle.
Long story short, you dont have to show any body but the ATF but its wise to do so unless you feel like being a total dick and refuse to awnser any questions.
People ask about my class III license all the time at the range....I usually say what license?
