Infrared lights attached to a hoodie can reportedly defeat infrared cameras used for tracking people on the street at night, so that they can't follow the person that wears the hoodie.

Tracking people's movements threatens human rights, so it is good to thwart tracking and surveillance cameras; it would be even better to prohibit them. By contrast, security cameras, which record their images locally in case a crime occurs there but do not allow remote examination, are acceptable because they do not make it feasible to track all the non-criminals.

We should require all cameras that watch public places to be the record-locally security camera type.
