Freedom of communication. In other words, "unreasonable search and seizure" extended to all communications. The same caveats - the authorities should be required to obtain an individual and targeted warrant before being allowed to (attempt to) intercept, and this should be granted only upon reasonable suspicion of a crime as determined by a judge. If they fail to intercept, they could always get warrants to secretly surveil the suspects, swap or backdoor their hardware, etc.
