Reword/rewrite the following paragraph.
The type of impact that an attack would have on public confidence would put doubt into citizens that our ports are secured. Even though ports and shipping containers have been used for a long time not many people pay attention to what's going on, but if a terrorist attack were to happen on a port everyone would be paying attention to what goes on in the ports. This could create fear within the public about the economy and the fear of following attacks on other ports.
