Certainly the U.S needs to stop the police killing people, but it also should treat people harshly for exploiting the 'people-killing' bug in their system.
If I figure out your internet of things refrigerator has a setting to add salmonella to chicken 25% of the time, and I then use an exploit to run the salmonella adding routine, the manufacturer should be sued for a lot of money for their stupid salmonella adding routine, and remove that routine. But I think you would agree that while my activity was similar to that time someone made your internet of things lights blink on and off, it was also more serious and I should suffer more for it.
If you know there's a strong possibility (and in the US, this is the case) that your phone call could result in someone's death - and calling in a fake hostage/murder to trigger a SWAT response certainly qualifies - you are part of the root cause, definitely.
> Blaming it on the caller completely ignores all other police killings that have happened without a swatter.
This is ridiculous whataboutism.
"The bug" is the fact that American police kills innocent people that have done nothing wrong. Of course the caller should be fined for abusing a critical service, but the root cause of this murder isn't in the phone call - it's US police killing innocent people in alarming number of cases. Blaming it on the caller completely ignores all other police killings that have happened without a swatter.
Unless you're trying to say that being able to call up men that murder someone is a feature desired in your country?
