There are a significant number of issues that are being looked at in terms of the study that's going on right now. Some of those issues address the technical issues; what are the standards? If you're going to mandate a particular type of equipment, what kind of equipment? What kind of reliability? What kind of durability of recordings, etc.? What's the positioning? What's the placement? What is the data that you want to gather? There are a number of areas to be looked at there.
There are also areas to be looked at in terms of the objectives of the safety and fatigue information, and what other kinds of information might come out of this. In general, what is attempted to be achieved with the use of the recorders?
Then there is the issue of how that correlates with the employees who would be subject to the surveillance of those video recorders. There's a good body of work out in the public and from the various privacy commissioners and others as to some of those issues, and they do come under a variety of umbrella legislation in other areas as well that should be looked at.
Finally, there are the regulatory issues and the legislative issues that would be required to put in place an appropriate regulatory regime. There are many questions to be addressed at this stage.
