"If police forces were strip searching white girls from fee-paying schools 75% more than other groups of girls, there'd be heads rolling."
Regardless of race, girls from fee-paying schools are going to live in areas with far lower crime rates so it would be very odd for their areas have the same level of policing and same rates of probable cause as other areas. Which is why earlier I said that drawing this as a category across the 9 million people in the London area (they never define in their report the area, they just say "London") was inadequate. You have to compare like for like if you're trying to isolate a single variable like race.
Also, just to keep things accurate, the 75% figure firstly is for all stop and searches, not strip searches. Secondly it refers to the number of cases that didn't go forward which despite the fact they must have this information and that it would be the most useful figure, they didn't compare for race. I'm not sure people who wish to demonstrate racism would actually want this figure to be any "better" as greater equality in further actions taken whilst disproportionality in searches remained the same would indicate that racial discrimination in searches worked. Which is hardly what I imagine you (or Open Society) are trying to show.

"The one thing I can say from this is that I don’t think children should be strip searched at all. I just don’t. It would have to be for reasons of their safety for me to support it at all."
It should certainly be done by someone of the same sex and in private conditions. But in the USA it was very common for adult drug dealers to send out minors to sell drugs due to their immunity from prosecution. I'll add again that these 110 figure was over the course of six years. You can't have a situation where anyone can just stuff some drugs or a knife in their knickers and be safe. I'm not disagreeing with you that there likely is more that needs to be done. But I don't go as far as you to say it shouldn't be done. I'd also argue that intervening in a kid being used to sell drugs at a young age is something that is for their safety (and their schoolmates as they'll be used to sell drugs to other kids).
If a police officer can say "Hand it over, don't make us strip search you," a lot of kids will simply hand it over. And "it" can be pot, heroin, a knife... "Hand it over or we'll just let you walk away," doesn't have the same effect when you gt into real policing. It's messy. I actually find 110 total strip searches across 9 million people in six years lower than I would guess.
