I read somewhere that Musk (or maybe Theil) companies have processes in place to quickly offload data from a location to other jurisdictions (and destroy the local data) when they detect a raid happening. Don't know how true it is though. The only insight I have into their operations was the amazing speed by which people are badged in and out of his various gigafactories. It "appears" that they developed custom badging systems when people drive into gigafactories to cut the time needed to begin work. If they are doing that kind of stuff then there has got to be something in place for a raid. (This is second hand so take with a grain of salt)

EDIT: It seems from other comments that it may have been Uber I was reading about. The badging system I have personally observed outside the Gigafactories. Apologies for the mixup.

That is very much illegal in the US
