The camera is not what's discriminating (in theory), it's the justice system that they have to deal with after the camera triggers on them.
To expand on what the above commenter said, the cameras are also discriminating because of the simple statistics of class dynamics. There are more poor people than rich ones being filtered into the justice system by cameras. Cameras also could be installed disproportionately in minority or poor neighborhoods, for example. Pretending that there aren't other discriminatory dynamics at play and acting like it's as simple as "tEchNoLoGY iS nEutRaL!" is ignorant.
traffic cameras in fucking Cornwall, this is where we really really need to draw the line and talk about systemic discrimination.
The world is larger than just Cornwall. Your bad faith reductionist arguments are idiotic.
You acknowledge that systemic discrimination exists, but you want to paint borders around where it's appropriate to talk about it. Why? Systemic discrimination is always worth examining. Yes, even in Cornwall, but also everywhere else.
there’s an extremely simple solution for not being „filtered into the justice system“: stop driving too fast
Nice how you conveniently ignore the other points made in this thread about how speed cameras actually are used. They don't call these approaches "speed traps" for nothing, there is intentional entrapment built into the system.
