A ballot in a ballot box is not secure either.
In my home town, the local “in” family had quite the time burning ballots to make sure their guy got elected.
Worked well till the “out” family hit them with a fire hose for burning inside the city limits. Got rather violent after that.
It does not matter who casts the votes, it matters who counts them.
Apparently, you personally knew of the fraud but did nothing to prevent it. You allowed a fraudulent election
