It&#x27;s pretty easy to find reasonable multiples on your assumptions. It&#x27;s London and they might not be average policemen: salary x2 ; Overtime&#x2F;nighttime: x2, Administrative overhead (they must spend time reporting, at the precinct, ...): x2 ; Multiple policemen (1 would not be enough to act): x3-x5 ; Management of those officers &amp; briefings: x2-x3 ; That&#x27;s already ~x100 and it&#x27;s human costs only.
