This is very pronounced at eg a federal building. At an airport, there obviously is a decent part of one's security that corresponds to the government's security.

The real problem, and why drawing the distinction is important even there, is that the government is choosing to do things that may or may not make government/group security slightly better because they/it cannot see a downside. When in reality it/they is hurting all the individuals' ability to take care of ourselves (eg my above description), even with respect to utterly banal threats like theft.
