If something specifically causes streetsams to go on killing sprees in which valuable property is destroyed and valued employees and customers die (note: the streetsam himself may be a valued customer) it gets pulled until the corps fix
There's your problem(s).
Chop docs, barrens clinics, organleggers, etc? Not corp. (some exceptions, like how corps set up in Lagos and test prototype augmentations on the locals)
Killing sprees outside arcologies and corp citizen compounds? Places where chop docs ply their business? Not quite as common as Tuesday, but violence is common enough that the cops don't go in the worse suburbs, nor do they step in until after it's done in surrounding areas.
Wonky wares? If we're talking Used/Omega, and we are, then the street samurai in question *chose* problems over costs. No rampage on discovery.
Haven't seen it yet and don't want to spoil it for myself, but I suspect there's not been enough streetsams massacring people in that timeline to be relevant to this conversation.
Can you tell from the pic that he looks old, scarred, and messed up? Non-spoiler alert. One guess as to why that is, and one guess as to what augmentation he has.
Also, 'not enough'? How many times have they tried to weaponise mutants in the xmen setting? How many times has that failed?
