I'd just say very briefly, dealing just with the powers of citizen's arrest, that I think the difficulty with the proposed changes is that a citizen might be unaware of the extent of his or her authority to perform these kinds of arrests because there's a presumption that citizens know the law, but we know realistically that they don't always understand the nuances of the contours of this authority. I suspect the same issue may well arise with the proposed amendments. Again, you're always dealing with some form of line-drawing exercise, and I think the concern exists, and the thing I would just add is that I think you're quite right in suggesting that what's being proposed here is an attempt to come up with a practical solution.
On this practicality point, it's important to realize what the practical implications are as well in terms of empowering very sophisticated law enforcement personnel who are these private security guards. I guess my view is that we know that in the Chen case the system worked. He was acquitted, even in the face of what was really a fairly aggressive arrest and holding of a suspect. So we know the system worked there. We look at the implications of these changes and I think that, on balance, maybe things are better left as is.
