United States, 1964, 118 U.S.App.D.C. 11, 331 F.2d 85. We will not consider those special cases. Neither do we consider when misjoinder may become an issue only during the course of trial. Schaffer v. United States, 1960, 362 U.S. 511, 80 S.Ct. 945, 4 L.Ed.2d 921; cf. Ingram v. United States, 4 Cir., 1959, 272 F.2d 567. We consider only the basic interpretation of Rule 8, viewed in advance of trial.
First, prejudice. Basically, even to try a single defendant for more than one offense involves prejudice, it being regarded as normally inadmissible, in determining whether a particular offense was committed on one occasion, to show that a similar offense was committed on another occasion. Macdonald v. United States, 1 Cir., 1920, 264 F. 733; Martin v. United States, 1942, 75 U.S.App.D.C. 399, 127 F.2d 865; Lovely v. United States, 4 Cir., 1948, 169 F.2d 386; People v. Molineux, 1901, 168 N.Y. 264, 61 N.E. 286, 62 L.R.A. 193; McCormick, Evidence § 157; 1 Wigmore, Evidence, §§ 55, 57, 194 (3rd ed. 1940). This is colloquially spoken of as. the “bad man” theory. McCormick, op. cit. supra; cf. Wigmore, § 192. Nonetheless, of course, there may be times when, even if the defendant were being tried for a single offense, other similar offenses could be shown, as bearing on intent, or on some other factor making relevance more important than the prejudice. For this reason “similar acts” is presumptively a more appropriate basis for joinder than would be dissimilar acts.
It may be equally prejudicial to try two defendants together. Because of the natural tendency to infer guilt by association, a defendant may suffer by being joined with another allegedly “bad man.” Here, again, no special prejudice may in fact arise from the joinder for trial, because the proof, even if the defendant were tried alone, might properly show his association with the other individuals. Again, Rule 8(b) is couched in terms which roughly cover or include this sort of case.
In these situations there may be little or no prejudice arising out of joinder. However, Rule 8(b) is not limited to situations in which proof of the other criminal transaction would be admissible in a separate trial. It goes beyond, to others, the excuse being the benefit to the court. But to offset the prejudice where multiple defendants are being joined even though they did not engage in a joint act, such as conspiracy,
Kitchell v. United States, 1 Cir., 1965, 354 F.2d 715, this possibility of benefit should explicitly appear from the indictment or from other representations by the government before trial. 'Classic examples of such a benefit are when there is an overlapping of issues, as, for example, when some defendants are charged with transporting stolen goods in interstate commerce, and others are charged with, receiving the goods, so stolen and transported, Kitchell v. United States, supra;
Caringella v. United States, 7 Cir., 1935, 78 F.2d 563, or when defendants are charged with conspiracy to conceal a crime that part of their number are charged with committing, United States v. Perlstein, 3 Cir., 1941, 120 F.2d 276 (rev’g on other gr’ds), 2nd convictions aff’d, 1942,
126 F.2d 789, cert. den. 316 U.S. 678, 62 S.Ct. 1106, 86 L.Ed. 1752. Where, however, there are no presumptive benefits from joint proof of facts relevant to all the acts or transactions, there is no “series,” Rule 8(b) comes to an end, and joinder is impermissible.
5 United States v. Spector, 7 Cir., 1963, 326 F.2d 345, 350; McElroy v. United States, 1896, 164 U.S. 76, 81, 17 S.Ct. 31, 41 L.Ed. 355.
Rule 8(b) is not to be implemented by Rule 8(a). For example, a single defendant, A, may be charged in one indictment with acts X, Y and Z,

While some cases seem to have gone a considerable distance in deciding what was a series of acts, see Wiley v. United States, 4 Cir., 1960, 277 F.2d 820, cert. den. 364 U.S. 817, 81 S.Ct. 47, 5 L.Ed.2d 47; cf. Cataneo v. United States, 4 Cir., 1948, 167 F.2d 820, 823, we find none that has dispensed with the necessity of a connection, or where one has been suggested on facts like the present.
