Swatting wouldn't even be a thing if <any number of logical things>
- Anonymous calls should be treated with high levels of suspicion as to their legitimacy
- First response training that's even moderately appropriate
- Situational awareness beyond what one's been informed by third parties
- Empathy for all humans
- Any kind of notion of that a scenario may not actually be as described by a single anonymous voice
A very (un)funny irony is that there are numerous stories I've read about domestic violence victims being arrested, as opposed to the attacker, which implies there's some level of suspicion in some circumstances about the information the police are being fed. Swatting, as a thing, indicates there's some kind of hero-pressure build-up that overrules any kind of <all the things I listed above> whereby that pressure has the possibility of impending release.
