established, for the court must still find that he is guilty beyond a reasonable doubt before it can convict. However, the accused's failure to present evidence on his behalf may be regarded by the court as confirming the conclusion indicated by the evidence presented by the prosecution or as confirming presumptions which might have been rebutted. Although not legally required to produce evidence on his own behalf, the accused may therefore as a practical matter find it essential to go forward with proof. This does not alter the burden of proof resting upon the prosecution (Wharton's Criminal Evidence, 12th Edn. 1955, Vol. 1, Ch. 2 p. 37 and foil). Leland v. State reported in 343 U.S. 790=96 L.Ed. 1302, Raffel v. U.S. reported in 271 U.S. 294=70 L.Ed. 1054.
