Security expert Bruce Schneier weighs in on the ridiculous airplane laptop ban the Trump administration and the British government imposed last week:
This current restriction implies some specific intelligence of a laptop-based plot and a temporary ban to address it. However, if that's the case, why only certain non-US carriers? And why only certain airports? Terrorists are smart enough to put a laptop bomb in checked baggage from the Middle East to Europe and then carry it on from Europe to the US.
Why not require passengers to turn their laptops on as they go through security? That would be a more effective security measure than forcing them to check them in their luggage. And lastly, why is there a delay between the ban being announced and it taking effect?
One analysis painted this as a protectionist measure targeted at the heavily subsidized Middle Eastern airlines by hitting them where it hurts the most: high-paying business class travelers who need their laptops with them on planes to get work done. That reasoning makes more sense than any security-related explanation, but doesn't explain why the British extended the ban to UK carriers as well. Or why this measure won't backfire when those Middle Eastern countries turn around and ban laptops on American carriers in retaliation. And one aviation official told CNN that an intelligence official informed him it was not a "political move."
In the end, national security measures based on secret information require us to trust the government. That trust is at historic low levels right now, so people both in the US and other countries are rightly skeptical of the official unsatisfying explanations. The new laptop ban highlights this mistrust.
But to the Trump team, distrusting government is a feature, not a bug. They just may not have thought through all the consequences.
