Human rights is another issue and on this they do very badly. They are among the worst places in the World to get arrested for basically anything and they have harsh laws that restrict all sorts of personal freedoms. But that's not corruption.
I still laugh about the interview I saw with Lee Hsien Loong in which the obsequious (although perhaps rather clever) interviewer asked him whether he had been upset when Goh Chok Tong had immediately succeeded Lee Kwan Yew (Hsien Loong's father) as PM. LHL squirmed and laughed nervously, and stammered, "Well, ah, of course not. One cannot have unreasonable expectations." Even he was embarrassed for his country then.
eg. "In 1991, the Junta laundered $400 million through a Singapore bank as down payment for Chinese weapons." - Jane's Intelligence Review ... or see http://www.theonlinecitizen.com/2007/09/singapores-debt-of-h...
If the men in power decided that Shane's death needed to be covered up, and the men in uniforms followed orders - then that is exactly how a non-corrupt police state works; you have strict order but that order doesn't neccessarily favor the people.
A corrupt state would have the relevant police officer be bribed individually and/or extracting favors from the relatives; corruption requires weak structure, where the system is centralised in theory but decentralised in practice, as decisions are made or changed by corrupt officials. But if the authority decides to do an evil thing and the system executes it without question - then that's a perfect example of an efficient, noncorrupt police state that achieves it's goals and spits at the costs.
Mexico is an example of a country with a lot of low-level corruption (you can bribe the police to get out of anything). The United States is an example of a country with very little low-level corruption, but with (arguably) lots of high-level corruption.
Singapore is a country with almost non-existant low level corruption in my experience (i lived there for a time and have visited many times), and their system is specifically designed to eliminate high-level corruption: they pay public servants high salaries and punish any corruption with very long prison sentences.
Not if the high-level law permits this kind of thing.
Whether the men in power are making the morally/ethically-correct decisions regarding this case is a separate matter altogether.

What I suggest is that the legal structure of a state might give it the option to approve and perform those things. You'd be surprised how many western countries have also invaded places or killed people for specific corporate interests that coincide with those of the state.
It's not as if they do it for the benefit of some small company. We're talking corporations with the level of influence and budget that's bigger than a lot of countries.
At least they did something about it.

* Singapore's Internal Security Act (ISA) and Criminal Law (Temporary Provisions) Act permit the authorities to arrest and detain suspects for virtually unlimited periods of time without charge or judicial review.
* The Misuse of Drugs Act permits the authorities to confine suspected drug users in "rehabilitation" centers for up to three years without trial.
* Outdoor gatherings of five or more persons still require police permits. The city-state's Speakers Corner -- where people may demonstrate, perform, and hold exhibitions -- remains the only outdoor space where uncensored speech is allowed in the country.
* The Singaporean government and senior government officials have frequently brought charges of "scandalizing the court," criminal and civil defamation, and sedition to silence and even bankrupt its critics.
* Singapore's 208,000 foreign domestic workers are still excluded from the Employment Act and key labor protections, such as limits on daily work hours.
* Human rights defenders in Singapore risk being fined, imprisoned, bankrupted, and banned from traveling outside the country without government approval.
