Six years ago today, a horror story unfolded.

The news came in of an explosion in Bidnija, and soon after, it became known that Daphne Caruana Galizia was the victim.

She was killed just down the road from her home by a car bomb. Malta's best-known journalist was murdered. It was a tragedy that changed the country.

In the years leading up to that tragic day, Daphne Caruana Galizia was the victim of a campaign that tried to make her out to be an evil character. So much so that some felt that they could get away with such a heinous crime. But that is not the case. Some have already been jailed for carrying out the act, while others are awaiting trial over their alleged involvement.

The outrage following her murder was unprecedented. People of goodwill stood up and said enough is enough. The news spread beyond our shores, across Europe and beyond. The call of Justice for Daphne is as loud today as it was six years ago.

A mother, a wife, a sister, an aunt... her family mourn. Nobody should ever lose a loved one in such a way.

It was a cowardly act.

Only once all those responsible for the atrocious act are jailed can there be justice.

But that is not enough.

Daphne Caruana Galizia was a leading journalist who fought against corruption and wrongdoing, and she had made many revelations in her writings.

Only by cleaning Malta up can we ensure that such a villainous act will never be repeated. Only by taking up her fight to weed out corruption and wrongdoing, change this country for the better and make sure that no culture of impunity persists would we really bring about change.

And we need that change. We also need better protection for journalists.

Daphne will not be forgotten, and her fight has become a rallying cry for those who want to see a better Malta.

But things are still not right in the country.

Aside from the lack of action against big fish in past scandals, with regards to a newer revelation, the big fish have not been charged so far.

Only those on the receiving end of the funds have been arraigned with regards to the disability fraud racket, as far as this newsroom is informed. What about those who organized it, who carried it out?

The Times reports sources as saying that investigators have now begun moving up the racket's organisational chain. We are still waiting for concrete action. All those involved must be charged in court, regardless of their identity.

As for the driving test scandal, three Transport Malta officials have been charged in court over the allegations and are going through the court process. But the Prime Minister has defended those in government and in ministries who were sending messages with the names of test takers as though it's a normal exercise. Well, Prime Minister, it is not right, it's not how things should be done, and playing it off as normal is wrong. You are trying to play the people for fools. But the people are not.

We need to get rid of clientelism, not embed it. The lack of political accountability on this issue is extremely worrying.

When it comes to driving tests, if someone is good enough to pass, then they should pass... if not, they should fail.

If there is someone who didn't deserve to pass, but was passed and ends up causing an accident... well then, that's also the fault of those who piled on pressure.

These are just two of the many other worrying revelations that emerged over the years.

A culture of impunity is what corrupted this country, what led to those who carried out the murder of a journalist to thinking they could get away with it.

We need real change. We need to strengthen our institutions.

Our enforcement authorities need to take better action when scandals emerge. Their salaries are paid for by us, the people. They must take action against both the big fish and the small. If those leading these authorities are not up to the task, then they must get out and make room for others who are.
