I still don't think their reactions were enough to warrant them hearing it. Can you imagine your high school class hearing about ******* ? I bet they'd flip their **** . These kids danced to something for a moment. I think a light came on showing it was activated like a webcam, but that's it.
In the full video he controls the camera with the directional pad on the left hand side. Also what ilovemyguns said. It's real. The kids probably wouldn't go that crazy as they're normies, its very racist, the teachers right there, and there's a black guy in the class.
Also... thinking about it. Its probably not so much as hacked... but an unsecured or easily exploited standalone camera... and I don't know but I don't think they can hear the sounds.
Cause this **** would of been all over the news and someone would of broke the camera the second they heard the word ******* .
