Obviously it is far better for Canadian society to have Criminal Code powers used appropriately. Police officers know how to make use of them because they know them well, the system knows them well and the guarantees work well in the context. Some mistakes have been made and there will be others but at least the system works in such a way as to provide enough guarantees of good results. It is reassuring for Canadians to know that there was evidence and that people were found guilty based on sufficient evidence. That is why it is a better approach, not only in terms of protecting human rights, but also ensuring that we are arresting the right people. It is of no use to incarcerate, arrest or detain the wrong people.
The idea of protecting the presumption of innocence is not simply in the interest of incarcerated people, but also that of the general public; we want to bring to justice the right people not the wrong ones.
