Choosing to bring devices full of encrypted noise vs choosing not to being devices is deliberately choosing to waste your time in addition to the CBP officers'. Maybe that's your goal, but they get paid to do that so you aren't exactly teaching them a lesson. If anything, you are just being rude to other people who want to cross the border since you've impacted the throughput.
It's sort of like "teaching the cops a lesson" by loitering around the local school in an ice cream truck implying something might happen.
It makes me think about illegal search and seizure, and how I guess that only matters for special people. It makes me think that, hey, maybe some inalienable rights are actually kind of alienable, depending on who you decide to alienate, right?
They get paid money to do their jobs. Well wowee! That means they're correct in fucking people up arbitrarily right?
Special person on a blacklist? Fuck 'em up! Don't like the looks of those guys? Fuck 'em up! Hate your job and need to take it out on somebody? Fuck 'em up!
Sure, I get that. But where does the black list come from? Can I vote on who gets listed?
You know, I got some people I'd like to fuck up, myself. Would that be okay?
What if I decide to hire someone to fuck someone else up for me? I got some money to pay them. At that point, they'd be doing their job.
Hmmm. Maybe I should pick a career that let's me fuck people up, just so's I can help write those lists. It'd be my job, after all.
Let's just humor the idea that, if they've got a job to do, they're obedient about it. Let's say, in this instance, the person harassed really is a piece of shit on a list for a good reason. Let's say that leaning on this guy and sending him a message was a good idea, for reasons I can never know about, but trust in that.
Okay, fine. He was the right bad guy to knock down a peg, so send a message. Sent him a message and he got it. Mission accomplished.
The point still remains: hobbling technical carry-ons like the laptop he has, and cloning handhelds to scrape for metadata intel is still a pathetic strategy which would only slow down a half-retarded script kiddie. It's a weak tactic that isn't going to offer real protection at any border, because that's not how smart people with technical skills approach a border.
If that's anyone's idea for how to interdict hacker operations and learn the details of their network, guess what. Consumer grade computers are likely a mere distraction in this scenario, and it's unlikely that a border agent is going to notice a device or technical object intended to survive a border search.
It's not likely that grabbing these sorts of devices stops the people that care about getting certain devices and data across.
Maybe raising the bar and taking ordinary laptops and handhelds off the table to advertise that it's not childsplay to bring general technology across a border might be another message to send non-professional trouble makers and problem children, such as in this case. Either way, to be honest, I think border patrol is out of their element and beyond their depth in this sphere.
Being a hammer, and approaching all border stops as nails, is a strategy for a century ago, when a pipe with a handle was surely a musket.
