Yes, they absolutely are. Just a couple weeks ago, local law enforcement sent out an incredibly vague shelter-in-place active-shooter alert across the entire Twin Cities area for a situation in a suburb that was resolved about five minutes later[1]. Schools were locked down, buildings closed, etc. And wouldn't you know it, there's an election in two weeks where the Republicans, who the police unanimously endorse and campaign for, are running on a "crime is out of control" narrative! Crazy coincidence, that.
[1] The entirety of the message was, "Shelter in place - Homicide suspect at large described as 17 year old white male." No location specified, sent to the entire urban region. https://www.startribune.com/shelter-in-place-alert-about-hom...
An honest mistake is an accident that isn't repeated, or if repeated, happens in a random manner rather than exhibiting any particular pattern (seems to express neither a conservative nor a liberal worldview, nor any other potential agenda, consistently).
If someone has a desire to do something like use some position or tool they happen to have access to for some purpose of their own rather than it's intended use, and lacks the integrity to avoid doing so on their own, that desire and that lack of integrity doesn't change or stop even if they get chastised for some misdeed. They still want to do things like that, and they still don't see what the problem is, and they still do the same things, merely trying to do a better job of camoflage and deniability.
This was completely useless and actually distracting considering that I was in heavy traffic at the time.
Some states will not send alerts overnight and others will; it is a matter of state policy - and ultimately an issue for the ballot box.
