Trying to find an international version leads me to ICVS and this[0] publication which likewise ranks London at the very top. By that data, the UK ranks average at per-capita crime but is second at the same people being victimized more than once, which I take points towards that the majority of the country is likely relatively normal, but a handful of cities have very concentrated crime rates that are raising statistics.
Do you have any other sources to show or do you just like pointing out that all of them are bad if they don't agree with you?

You'll also note that the paper itself then provides data from additional capitals that it's conveniently not included in the main list. Several of those additional cities ranking above London. In other words, it's a sample that even the paper demonstrates isn't remotely comprehensive.
I don't need to provide any other sources - you're the one that made a claim that was based in "data" that was entirely worthless, and this new data still isn't even close to backing up the original claim.
