How does London's spate of killings compare with other cities?

A spate of recent suspected murders in London has prompted concerns about rising levels of knife and gun crime in the capital.The total in 2017 was 116, excluding the deaths in the Westminster, London Bridge and Finsbury Park terrorist attacks.One of the more eye-catching comparisons has been with New York, presumably because it is etched into the public consciousness as a place associated with high levels of violence.
