That is such a difficult question. I think in principle I would say that there ought to be obligations, whether they come through the charter or through some sort of parallel provincial legislation or otherwise. I think there certainly has to be some sort of accountability akin to that, which we see with the charter.
The problem, though, as Professor MacDonnell noted, is that especially for your David Chen type of scenario and not your sophisticated security personnel, in practice it may be difficult to implement these obligations, such as the right to counsel or the right to silence. I think there's a fairly solid common law to suggest that citizen arrestors are obligated to provide the reasons for arrest, and that's very similar to what paragraph 10(a) of the Charter of Rights and Freedoms says, but whether or not the panoply of charter rights apply is difficult when you come across the unsophisticated arrestor. I think in principle I agree that there should be accountability akin to that in the charter.
