Completely agreed. The fourth has the more clear-cut 'bright-line' demarcation point, as you said, "the government may not randomly search people", whomever those persons are.

Clearly though, not all rights in the bill of rights can be held to the same standard... for instance, voting rights should not as clearly be extended to non-citizens who just happen to be on American soil, but one's right to life had very well ought to be.
