that could be defeated with a simple UV filter over the camera lens, likely already in place
ir camera jamming is doable and well-known enough to appear in media like crime dramas
none of it is very practical because you're still extremely identifiable as "that one with all the lights" and presumably still visible in the visible spectrum
when police jam cameras at protests they just use bright visible strobes
Glass and plastic typically used in camera lenses already blocks UV. Enough UV to upset a camera would be enough to give you cataracts.
Infrared is a different story but most cameras have IR filters. Security cameras sometimes have one that only drops in during the day to enable daytime color and nighttime IR.

Ironically then the story just goes from "here police are brutalizing the people protesting brutality" to "and also being childish with their flashlights." Bright lights aren't nearly as blinding to large-sensor cameras with good lenses as they are to cheap cell phone cameras.
