I think I should address this.
folks, you have to let go of the notion that people over the phone whom you call are perfect people. They're trained, but they're not perfect. They're human. And if that human hears a voice that sounds serious enough or even scared enough, they will assume the call to be genuine because that makes sense. Now, they're trained to look for slip-ups, no doubt, because prank calls have been a thing for a long-ass time, but some emergency service skepticism has also led to people with legit concerns not getting help. The second-guessing can hurt. So, with that in mind, some people WILL be fooled, despite all the best efforts. They're not idiots. Other people are just that convincing sometimes. The bad thing is that that means this shit can't be wholey prevented. The GOOD thing is that this bill is a viable deterent, and that anybody who is that convincing while being a prankster eliminates the ambiguity of the crime. They did it, on purpose, no question.
