I think Mr. Chris Case said earlier that the availability of specialized equipment to respond to an incident varies from one municipality to the next, depending on its fiscal capacity and budget. So even though there are some very dangerous goods going through, cities don't necessarily have what they need to adequately respond to situations that may arise.
In a way, this is a transfer of risk since cities are now responsible for protecting themselves against such situations. Do you think it's normal for cities to assume all the risk?
