This event, described at the end of the article, does not sound like a "casual, minimally invasive search" to me:

"At an Amtrak inspection point, Pascal Abidor showed his U.S. passport to a federal agent. He was ordered to move to the cafe car, where they removed his laptop from his luggage and “ordered Mr. Abidor to enter his password,” according to the lawsuit.

Agents asked him about pictures they found on his laptop, which included Hamas and Hezbollah rallies. He explained that he was earning a doctoral degree at a Canadian university on the topic of the modern history of Shiites in Lebanon.

He was handcuffed and then jailed for three hours while the authorities looked through his computer while numerous agents questioned him, according to the suit, which is pending in New York federal court."

I definitely agree that electronic searches are nonminimal and highly invasive.
