Officers only started keeping the league table after a blameless man was shot dead.

The story

Police who have seized guns, knives and vehicles following the fatal shooting of bus driver Auguste-Marie Bile-aka Amoa, 25, warn that vengeful gangs are keeping a tally of tit-for-tat violence using football-style scores. Bile-aka Amoa, who Metro understands was blameless, was shot dead in his car in Clapham on 10 August. The crackdown that followed has led to more than 400 arrests. Det Con Faisal El Issaoui, the Metropolitan Police's expert witness in court on the activities of London gangs, said: "Young boys are dying on the street. There are memorials all around the patch to them. It's terrible." He described the rivalries as operating like "a game" with a league table, where a murder scores a maximum three points and a non-fatal stabbing one. Det Ch Supt Emma Bond said gang violence and tensions are rising faster in this area of London than others, adding: "That is concerning and that is why we have this targeted approach."

The reframe

More than 400 arrests, firearms recovered, an embedded Metro ride-along with the Met's own expert witness on London gangs: this is enforcement operating at a scale that photographs well. It followed one death, that of a bus driver Metro understands was not involved in the rivalry that killed him.

Det Con El Issaoui's account of what preceded this crackdown is the part that does not photograph. "Young boys are dying on the street," he said. "There are memorials all around the patch to them." Memorials imply a pattern that predates 10 August by some distance, a landscape of prior deaths absorbed into the ordinary texture of the postcode rather than treated as the trigger for 400 arrests. Auguste-Marie Bile-aka Amoa's death was not the first violent death these officers had encountered on this ground. It was the one that made the response arrive in this form and at this scale.

The distinction matters because it locates the trigger correctly. It was not the general pattern of gang violence, evidently ongoing long enough to generate memorials, that produced this operation. It was the specific fact that the person killed was, in Metro's understanding, blameless, caught in a rivalry over territory he had no part in. A death that fits neatly inside the existing rivalry, one gang member against another, does not carry the same political weight as one that spills outside it. The scale of the response tracks the visibility and unacceptability of the individual death far more closely than it tracks the underlying rate of harm the detective describes as normal enough to have generated a scoring system.

Det Ch Supt Bond's description of the approach as "targeted" is accurate in the narrow sense that it is aimed at named gangs on named streets. What it does not explain is why a rivalry organised enough to keep a running league table of stabbings and murders, one gang member told Metro they use terms "like we've got 1-0, 3-0 or 3-2", required a bystander's death to attract 400 arrests rather than the pattern of violence the table itself was already recording.
