Background of the recent Riot and Thoughts

Here's a summary on what led to the recent riots in Dili.
Background: Soldiers from the west of East Timor claimed that the army favoured the eastern side of East Timor; that the western side are not given proper facilities and overlooked in promotions. These soldiers left their barracks and held a protest in February. The commander of the army warn them to return to their barracks or faced the axe for indiscipline. Some returned but 591 did not and they were sacked. These sacked soldiers then appeal to the president to look into their case(of discrimination). However, the government was slow in setting up a committee to investigate and on the 24th of April, the soldiers held a 5-days demonstration(approved by the government). Before this demonstration,there were already some trouble in Dili; some stone-throwing, fights in Taibessi market and a stabbed ploiceman.

Riot: The 5-day demonstration were peaceful for the first 2 days but got worse on wednesday and thursday. On the last day of the demonstration(28th April), the situation worsened as the ex-soldiers were not satisfied with the government's answer. Many of those who joined them(we called them the third party or hooligans) in the demonstration began to caused trouble by burning vehicles and throwing stones near the government building. It got worse when they started burning shacks and houses in the Tasitolu area. The riot was quickly quenched as riot police and the military sprung into action. The riot resulted in about 100 burnt buildings, some damaged and burnt vehicles, at least 5 persons killed and more than 50 injured. Some locals claimed that more than 50 people were killed in the shooting in Tasitolu.

Aftermath: In the District of Ermera, third parties surrounded a government office in Gleno and killed one policeman and injured another one. It came as a surprised as all the troubles were happening in Dili only and many people consider the other districts to be safe. There are now rumours that they will be further trouble.

My Thoughts
Who's at fault: I would say the government. They should have addressed this issue in the first instance by responding to the protest and reassuring the soldiers that they will look into their grievances. Timorese soldiers are still new and some of them are guerilla veterans who might still not be used to army discipline. If the government had responded, there will not be sacked soldiers and certainly not a demonstration that was blown out of proportion into a riot.

Questions: Then again, no one really knows what's going on beneath all the decisions and politics. Could it be that someone overlooked the protest intentionally? Is there really a plot to overthrow the government as the PM claimed? Could this be the catalyst to the supposed coup? Will East Timor be returning to the days of unstability? Everyone is waiting for an answer.
