Italy: Laser pointer used at Venice film festival to point out viewers without masks
A story about the Venice International Film Festival mentions that ushers in the theater were using lasers to point out persons who lowered their COVID masks in the dark, after the film had started:
"Mask-wearing was one of the most assiduously policed protocols; even mid-row offenders were publicly shamed by being immediately targeted with a red laser pointer, which must have felt like being in the sights of a sniper."
From the New York Times
COMMENTARY FROM LASERPOINTERSAFETY.COM
This is an interesting practical use for laser pointers. Of course ushers should only use a low-powered "bullet" type pointer like those sold in pet stores, that take two or three hearing-aid style batteries. Care should be taken to avoid the eyes. If the beam from a small Class 2 (less than 1 milliwatt) laser accidentally goes into a person's eyes, there would be a bright flash but no injury or damage.
