Malicious contact after scoring

[DG]

This is all very interesting. It is possible to score, and then create malicious contact, and not be called out for the malicious contact. But the runner would be ejected. But on the play in question:

On a force play, the runner has an obligation to legally slide up to but not beyond a base, or avoid the play entirely. R1 did neither, so he is out, and the double play is enforced. Since he made malicious contact he is ejected. Since the double play was enforced no runs score. Even if there were no outs, R1 and B1 are out, double play.
