Less fun than baseball, but potentially a lot more dangerous to individuals, is the possibiity that the content of one’s cellphone or other device could be searched (either by law enforcement officers or by crooks). Fortunately, there is currently a lawsuit in process against the apparently unreasonable searches and seizures performed by customs and border agents.
Fortunately for those not interested in lawsuits, and want some things to do now to avoid the hassle of having officials search their devices at airports, there are some measures that may be helpful. For some months passengers from eight majority-Muslim countries had to put their laptop computers and tablets in their checked luggage, so presumably anyone could do this, and include their cellphones as well. (Yes, we realize that for many people, especially millenials, their cellphones are their Gods. But checked luggage rarely goes missing these days, so this may be the lesser of evils.)
