Agree with the two previous posts.

When I was arrested the prosecution asked that I be incarcerated without a bond hearing for the maximum time allowed under the Patriot act, six days.  One of the reasons for this pre-bond hearing incarceration was to make sure I did not move my funds before they had a chance to find them.  They were very concerned that I might move my Bitcoins out of seized wallets on seized computers before they had a chance to find them all and move the Bitcoins to their own wallet.

ASSIDE:  I found out later that their wallet was a Trezor that they had seized in another case.

The judge initially granted the prosecution's request for a six day hold before the bond hearing.  My attorney, after getting his mandatory $50,000 cash retainer, did successfully argue this and I was given a bond hearing and got out on bond after only four days and three nights in jail.  I assume I would have survived another few days being bored to death in solitary confinement but it would have totally sucked.

By the time I was released on bond they had found and had moved most of my Bitcoins, the Bitcoins I was holding for my non-tech savvy parents, and some other Bitcoins that were not mine (was holding for a friend until he got his own Trezor.
