My security threat profile was common burglary and my main concern was making sure my wife would be able to sell the Bitcoins in the event of my death.  So, the the vast majority of my Bitcoins were kept in a Trezor Bitcoin safe with the seed words kept off-site.
After searching my house for many hours and not finding what they were looking for, but taking every computer and electronic memory device they could get their hands on, they phoned in a search warrant for my office, which was granted.
Upon searching my office they found my off-site paper backup of the seed words for the Trezor which were there with retrieval instruction in the case of my death.  They took all of our corporate computers and left.
The rest is, as they say, history.

Food for thought:  my attorney informed me that they can and sometime do put people in jail until they turn over a password.  So in reality your passwords are only as safe as your willingness to spend time in jail over them.  After spending 3 days and 2 nights in solitary confinement (in the SHU at the federal detention center) I can tell you that most people will crack in pretty short order.  It boring beyond comprehension.

Part of the total cost shown on my wife's web site ($284,373.00) was the cost of replacing all of the computers and cell phones we needed in order for our business to keep operating.  Of course once we get all the computers back we will then have more computers and phones than we know what to do with.  Anyone want to buy a used computer that was under government control for nine months?
