I must assess the situation in Ottawa (I may write about the airport, highways, railways, bus station, embassy, ETC). To look at it from security and engineering prospective (let say someone wants to blow it up, how it would likely to be done and how we are going to protect it). As an example- you may review the American Embassy and start analyzing why it is a bad location, the possibility of the terrorism act there and so on, can you please give me some example and why the location of this place that came to your attention in important to study rather than American Embassy because other colleague already took this topic! Many thanks
