The use of these vans seems like an opportunity for some investigative journalism. Setup dosimeters to detect the x-rays as the vans pass by, record a video of it happening, then tell the pedestrians nearby that their government just irradiated them without their knowledge or consent and see what they say in response. Or setup stands that detect the x-rays and automatically announce over a loudspeaker that people standing nearby are being irradiated an observe the reaction. If the police are not confident that the responses will be welcoming, they should not be doing this.
