Workers' Party rally 2- Your vote is secret!

I was at the Workers' Party rally at Serangoon Stadium. Here are a couple of shots from my ordinary iPhone camera.
Like the first rally, I reckon there were about 50k people in attendance. Pretty amazing.
The key point that was driven home tonight is that your vote is secret.
1) You place your votes on poll day. Note that the serial number is just to make sure one does not vote twice.
2) Votes are taken to counting centres. Votes are counted by civil servants from different departments in full view of candidates from each contesting party.
3) Ballot boxes sealed and party members will sign on the seal. They are then taken to the vaults in Supreme Court and locked up for six months.
4) After six months, the sealed boxes and signatures are inspected by all parties and sent to the incinerators. Members of all political parties will be present to witness this.

There is no way your vote can be traced.
So you see, vote without fear!
