Does it not show a disproportionate percentage of blacks are involved in rape? I just want a bit of honesty in the debate, not an exercise in PC.
I don't think we have the information necessary to judge if the percentage is disproportionate. (ETA2: Prima facie, though, it does seem high.)
However, the figures clearly do not say that 92% of the rapists taking part in gang-rape are non-white.
8% of the
gangs were all white
24% of the gangs were of mixed ethnicity. Some of those rapists may have been white.
32% of the gangs were all-black
36% of the gangs had no specified ethnicity. Some of those rapists may have been white.
We can say that between 8 and 68% of the gang-rapes involved white rapists.
I don't think we have enough data to begin to guess at the proportion of white or non-white rapist taking part in gang rapes. Well, we can probably set some limits, but they're going to be wide.
ETA: (Pressed "Submit" too soon.)
We don't have the breakdown on numbers involved in each gang-rape by ethnicity (it
could be that rapes involving white men had 6 participants). It's not clear to me if they're counting anything apart from white and black (from the victim breakdown, though, I think they may be). We also don't know if each of the 93 incidents were perpetrated by different gangs; if all the white-only rapes were by the same gang, but the black-only ones were by different gangs (or vice-versa), that would skew the percentage of rapists who were white.
All that said, it may well be that there is a greater propensity for black men to take part in gang rapes than other ethnic groups. If so, the reasons need to be understood, and something needs to be done about it (though that applies to the problem in general).
All of which is to say that there is nothing in the figures to support the headline "92 percent of all gang rapists in London are non-white". It could be true; the figure could even be higher; you simply, unless I've missed something (and I admit i have only skimmed the data), cannot tell.
