But the government is going to claim that its "right" to get at the evidence is stronger than the property rights of the other co-resident users.
Consider: the 4th Amendment isn't in effect when you're within 100 miles (?) of the border; the chance of smuggling, etc., is greater there, so the need to detain and search people in that zone outweighs our rights. Or, consider a case in which my buddy borrows my car, and is seen driving through an unsavory neighborhood, is stopped, and found with a big sum of cash. This gives them the "right" to confiscate my car because it was involved in drug trafficking, even though no crime has been committed, and I wasn't involved in any case.
My understanding is that the CBP and immigration officers can work anywhere within 100 miles of the border ... or of any port. Which includes airports and general aviation fields capable of receiving flights from outside the USA. Which means just about anywhere.
However, that particular issue is not germane to the case in point, which appears to involve the FBI rather than immigration/border patrol.
Wow, I'd better avoid all the hosting companies that repeatedly fly my data through TSA!
Just because the government has the legitimate right to conduct warrantless searches under conditions {x,y,z} doesn't mean they have rights to conduct warrantless searches under any other condition, or under all conditions.
