Questions for the ridiculous number of people on here who are perfectly willing to give up their right to privacy because you believe it makes schools and other places safer:
Have you read the 50+ page user agreement for your cell phone company? How about the user agreements of every app that has access to your cell phone, your PC mic or apps that have access to your files? Late model cars have microphones too, as do TV remotes. Microsoft has access to everything on your Windows PC. I'd give 100 to 1 odds that 99% of you haven't read any of those user agreements OR the UA for private chat apps you are using. Likewise are you sure any cloud storage you're using isn't scanning your documents for forbidden phrases?
Since you haven't read every word of each and every user agreement and think it keeps schools safe, you should be just fine with the fact that EVERYTHING you say or write may be available to law enforcement, even if you're talking to yourself while sitting on the toilet in your home. If you mutter that you'd like to kill someone or burn something misheard as a school building to the ground you are just fine with AI flagging it and the police knocking on your door in an hour, right? You'll also be just fine with losing your career and your job never being able to find another one, right? Right? After all, other people never know WTF someone dangerous and violent is going to do.
The number of people on here who are perfectly willing to give up all their rights and have their private communications monitored for something that is nothing more than security theater is unbelievable.
