The Swedish traffic agency, in combination with the health department, openly publish accident data for every road. Accidents and their outcomes are public data and has been so for a long time. The location of traffic cameras is also public and so is the date when they got installed. Everything is open to the public, and gps applications are allowed to both have the data and warn drivers.
The accident rate from before to after the installation of a camera has an average reduction of around 25% in reducing deaths in traffic. If someone don't believe it they can download the public data themselves and redo the math.
Sweden also do not have traffic cameras on highways, most likely because they are ineffective in reducing deadly outcomes at those speeds. The chance of surviving a frontal collision at 100km/h is highly unlikely, so the cost of installation a camera is better spent on roads with lower maximum speeds where the reduction in average speed actually have an effect on outcomes.

Try to forbid movement in the area and you can reach 100% reduce in deaths.
Statistics and data doesn't tell you the whole picture and often skewed.
Most crimes in Sweden are committed by "refugees" by huge margin, but good luck doing something about it or let alone talk about it publicly. But hey, lets install another camera to have everyone to slow down and exacerbate traffic conditions further down.
