re: SCOTUS isn’t going to mess with immunity

"Judgment in cases of impeachment shall not extend further than to removal from office, and disqualification to hold and enjoy any office of honor, trust or profit under the United States: but the party convicted shall nevertheless be liable and subject to indictment, trial, judgment and punishment, according to law.

Only if convicted through the impeachment process can the President be liable and subject to indictment, trial etc, note the utilization of the colon. If impeachment isn't a requisite, then how does one convicted of a crime, then get indicted and tried for the crime? Non-seqitor.
