A gang of four armed raiders held up an English Bitcoin trader at gunpoint. He was forced to transfer a large sum in Bitcoin. I believe this is the first such event in England, but not the first in the world.

How can we protect ourselves against this? Some thoughts occur to me.

Transfer the coins into a timelocked wallet controlled by me. But would that provoke a physical resction from the raiders.
Time lock the transfer into their requested wallet.
If the stolen coins are run through a mixer, could I sue the mixer because he was profiting from the proceeds of crime.

Has anybody got any other ideas?
