You are completely and utterly wrong. That's not surprising though considering that most blanket statements are.
For starters, the problem with inquiries is that lawyers and judges know very little about the issues they are dealing with. Take the Somalia inquiry. Anybody with any background in the military knows you don't take a group such as the Airborne and send them on a peacekeeping mission. THAT was the mistake.
Secondly, the political system is run by the legal system. Hiring judges to investigate is like hiring Tie Domi to investigate fighting in hockey.
Thirdly, because of the public nature of the inquiries, political sensitivities always carry extra weight. Look at the Braidwood inquiry...the biggest problems on that day was the low hiring standards of the RCMP and OH&S legislation that indirectly governs the training of these officers. It was and is politically unacceptable for either the government or the police to publicly state that the officers are not competent.
Fourthly, the set up by their very nature make inquiries a poor way to uncover problems. By making it about "who" is responsible, the ass covering begins as soon as the word inquiry is uttered publicly. A lot can be learned from the NTSB. When airline crashes are investigated, they are less concerned about afixing blame and instead, are more interested in how or what to change to make the event less likely in the future.
What we really need is somebody outside of the issue to do an investigation...somebody not involved with government, the legal system or the military. Doing it publically tends to make those with important things to say clam up.
Public inquiries are about the system.. Of course they are run by Lawyers, Judges and the court system as that is what our Parliamentary system is based on.. What kind of independent outside person would you want to review the process ?
Asking Tie Domi to investigate fighting in Hockey would be the best to stop fighting if you asked him to do so in the appropriate way. It is not what you ask Tie to investigate that is the issue but rather what you want from him. Just like asking hackers to protect your computer system from other hackers.
Most Inquiry had issues because people do the ass covering before the Inquiry starts. The Inquiry is tainted way before the process starts.. That would be no different if you had an independent outside person.. The problem with the process is that it is much easier to bias and independent person then a full inquiry and in most inquiries we have always had some truth come out in some form.
I tend to disagree that doing a public versus closed door investigation offers more information. There is no statistical proof that people discuss such topic more open in closed doors versus public scenarios so its a moot point..
The last issue we have in this case is that the Government would block all documents relating to Military issues due to NATO related security clearances that would make this independent investigation totally useless.. Any investigation would get Zero documentation..
