Father and Son to face death penalty for killing robber at home

Father and Son to Face Death Penalty for Killing Robber
When I read the headline in our local paper and asiaone of Singapore i was like, Wow! What? and then with much emotion - Why are the victims being charged? Haven't they being through enough having been slashed at and now the Police want to charge them for killing an arm robber in the midst of defending themselves?

(Anyway, the latest news is that the father and son duo sentence will be reduced to death by negligence.)

to death by negligenc

There are still lingering questions unanswered.

From the picture of the newspaper report here, it shows that the father and son duo are handcuffed. And in Malaysia you will be handcuffed only if you are being arrested.

Question is -

1. Was there a forensic finding on the spot that confirmed that the assailant was beaten to death only after he was tied up? Can that be technically concluded on the spot?
2. If not - on what basis was the father and son being handcuffed and treated like a common criminal when all that they did was to defense themselves? 
3. Based on a report on malaymail online it quoted a lawyer who says that  in the Penal Code "anyone ......has the right to protect him or herself even if it results in the death of the assailant.  But then of course I believe there will be other contingencies that may negate the above.
4. Was due diligence done on the situation of the moment of the incident before the decision was make to charge the victims for murder?
5. Who decides to charge the victims for murder?

I have to ask the above because the report from the newspaper have left out pertinent information leading up to the victims being charged for murder.

Without those information the public would naturally felt outraged for the seemingly injustice done on the victims and the indifference attitude of the police who see it necessary to handcuffed the victims whose wife was slashed by the assailant!

The public tend to relates to the victim situation as most of us have read about individuals being slashed and robbed by armed men in the ATM vicinity, petrol stations, in our house, driving a motorcycle or even walking on the street - and most of the time we have never heard that these robbers are apprehended or brought to justice in a court of law while some of their victims remain in hospital or have died.

And just as we read about the table being turn on a robber the Police have to announce that the victims will be charged for murder!

Can you beat that?
