It strikes me that the original Franklin quote really identifies a specific case of the availability heuristic. That is, when you're focused on safety, you tend to adopt policies that increase safety, without even considering other values such as liberty.

There may also be an issue of externalities here. This is really, really common in law enforcement. For example, consider civil asset forfeiture. It is an additional legal tool that enables police to catch and punish more criminals, more easily. That it also harms a lot of innocent people is simply not considered because their is no penalty to the police for doing so. All the cost is borne by people who are irrelevant to them.
