That depends on how good they are. Full disk encryption can prevent access
if they power your machine down without taking measures to copy what is
in memory (to retrieve the disk keys). A dead man system can deal with
leaving it powered up for too long.

If you are running a gambling operation or the like and can afford to have
a trusted person available at all times to react to a raid, you can arrange
for memory to be cleared in a very short period of time. You should have
enough time even in a no knock raid.
