Do We Need To Be This Scared?

I was with a friend a few days ago. She is planning a trip from Seattle to Chicago by train in July. She's 'old'; she's 76 or so. The train trip sounds fun to me and to her! Some of her other friends have advised her to get a burner phone (Gjohnsit posted a comment about these a few days ago) and a burner laptop, with nothing on them but maybe games, in case she's stopped by the police or TSA (really, on an in-country train trip?) and she's detained and her phone and laptop are confiscated and searched because she is 'suspicious'. Do they actually do this kind of searching of people on trains as well as airplanes? Any passenger? I've not heard of it happening on trains, I have to admit.
