Hand-counting is done in public in any respectable democracy. Each ballot is shown and you can constantly see the current tally. My parents used to take me to our polling places tally when I was a kid. For a mistake to happen, thirty persons supporting different candidates would have had to be wrong at the same time. It seems very unlikely to me. Also, my country manages to hand count 30,000,000 ballots in less than two days and we get a very accurate result prediction on the day of the vote using a sample of official results from small polling places known to be representative. Hand counting is not a problem at all when implemented properly.
