I must say at the outset, Mr. Laframboise, that we look at transportation safety generally by means of risk management. In other words, we ask questions about the likelihood of one event happening rather than another.
I will illustrate what I mean by giving you an example from public transit. If, as a terrorist, you are thinking of a particular target, it is very likely that your intention is to produce the maximum effect. The event will happen in a major centre rather than in a smaller one, where fewer people live. You would probably want to advertise what you are doing by making some grandiose gestures. The same reasoning applies to risk management. We invest in those sectors that are the most likely to be the target of an attack.
Inspections are carried out at irregular intervals to avoid having them become routine for the organizations in question. We proceed by sampling, but it does produce results and allows us to make corrections if necessary.
I will ask Mr. Grégoire to give you some more information about the inspections.
