Seriously, though. The idea that the police can make you give them your password is ludicrous; if they have probable cause, they can get a warrant, just like for your house.
And just like with your house, if you don’t let them in, they’re perfectly capable of busting down the door.
It’s just that in this case, “busting down the door” is a wee bit more difficult.
I am curious, though. If you refuse to comply, can you be held in contempt and jailed forever? Or at some point does that violate your 8th amendment rights?
