+A non-obvious problem:
 
 \begin{itemize}
-\item acquired a machine from an anonymous source\medskip
-\item the source code running the machine was tried to keep secret\medskip\pause
+\item you can nowadays get old machines, which still store old polls
 
-\item first reversed-engineered the machine (extremely tedious)
-\item could completely reboot the machine and even install a virus that infects other Diebold machines
-\item obtained also the source code for other machines
+\item the paper ballot box needed to be secured during the voting until counting;
+e-voting machines need to be secured during the entire life-time
