Should I call the owner of the seedphrase careless or stupid? I guess he's both... Why would one risk the security of his funds by taking it around written on a piece of paper? I wonder if he has some coins on that because if he does, before he must had realised this video his coins must have already been moved... One lesson here don't always try to be too safe with your seed... Write it down and store somewhere safe..it shouldn't be around you all the time...
We can't completely blame the guy for that mistake; it could be that he's just trying to relocate, or one thing could lead to the reason why he has to move out with the seed phrase. He accidentally bumped into those officers, who took the opportunity to violate his human rights.
If there is anything they are searching for, they should not have been going right up to a piece of paper when the person is not under investigation whatsoever, and secondly, if the guy in question is wise enough, as soon as he's freed from that place, the first thing to do is to empty the wallet himself and move the holding, if there is any, to another wallet.
