I wouldn't hold anyone for keeping their coins safe in anyway they feel it's best, it's a good thing that this OPs friend react very fast like that, even if it was possible that those cops have their ways of extraing recovery seed he have just escaped the hack already, don't blame him for reacting that fast even though it's clear that they don't understand the hardware wallet. Since this person's bitcoin remains intact it's all well and good, people should focus on learning from what this person did, if that wallet isn't a hardware wallet maybe people will be praising that person, anyways, he reacted correctly and I like that.
That's right, somethings don't need one to get to a comfortable place before they do the right thing, assuming he didn't react correctly, he won't have un- lose his coins and mistakes like this, that most people do fall for and they might not be as lucky as this guy, so people should be aware of the kind of wallet they can use that will keep their funds safe, because when something bad happens, especially if it involves their funds, they will be so pressured that they can even act rational and still make mistakes while doing the needful, people can help themselves by avoiding getting to a situation like this before taking the right step.
