As for the no-fly list, I guess it’s like they always say, innocent until proven guilty, or until placed on a secret government list for unknown reasons with little hope of appeal.

In case you missed the news, Canada’s no-fly list went into effect on Monday. There are up to 2,000 people on the list — 2,000 people who are an “immediate threat to aviation security” but haven’t, you know, actually done anything we can arrest them for.
