Sure. I can start with a response with regard to the barrier question.
With regard to bus operator barriers, we have had some experience here in Vancouver where we were ready to install barriers in all of our buses to prevent people from actually getting to the operator to assault them. Unfortunately, or fortunately I guess, it went to a vote of the bus operator union and they actually voted against the installation of the barriers.
The common comment from the bus operators was that they actually enjoyed the customer contact they have each and every day and they find that to be the best part of their job. When the barriers are installed it eliminates that actual customer contact. As a result, it reduces their impact in the community. They wanted to be able to continue with that and were actually willing to take the risk of being assaulted in order to continue with the best part of their job. That is why the bus operator shields have not been installed in the metro Vancouver area.
