After student arrested for carrying laser-pointers, Hong Kong protesters stage "stargazing" laser-protest

Both Hong Kong protesters and cops have taken up laser pointers in support of their goals; protesters have used them to blind CCTVs and pinpoint vigilante thugs who assaulted them; cops use them to identify targets for snatch-squads.

The police have claimed that the lasers have caused eye damage to officers, and have classed them as offensive weapons. A student was arrested for carrying several laser-pointers, and that set off a mass laser-protest whose participants styled their action as a "stargazing" event as they flicked their lasers over a domed building.
