I concur in the reversal of the judgment on the issue of. penalty. I would also reverse the judgment on the issue of guilt under the compulsion of Griffin v. California (1965) 380 U.S. 609 [14 L.Ed.2d 106, 85 S.Ct. 1229], and Chapman v. California (1967) 386 U.S. 18 [17 L.Ed.2d 705, *75987 S.Ct. 824]. (See also Ross v. California (1968) 391 U.S. 470 [20 L.Ed.2d 750, 88 S.Ct. 1850].)
