Be careful with the display of these artifacts.In 1971 a US citizen was reported to have grenades to the ATF.
They raided his home and when he heard the break in he responded with a percussion pistol and he was shot in the head.
His name was Kenyon (Ken) Ballew. It just goes to show you that you can never predict how an informant and your government may behave.
The consequences for an innocent person can be severe.
