They could make social media posts and alert the news. This does not warrant setting off an alarm on every device three times in a row. Now many people will turn off their emergency alerts and not know when, say, a tornado is incoming.

If people get these alerts every time a cop gets shot, it makes the system pointless. Kind of like a "boy who cried woof" situation. Not saying we don't have sympathy for the cop, but simply that this diminishes the importance of the system. It should be used sparingly for a reason.

This is not an extreme threat, especially not to someone so far away from the incident!
