>>Not everyone gets a call to be investigated. What should the police have done?<<
Perhaps ask the lady who called them what the guys were doing that caused her to call them? Your assumption indicates that I could call the police to come investigate you and it would be you who gets harassed. Shouldn’t I be asked to give a reason I am asking them to come out?
I think the lady should be cited for a false report. The guys were doing nothing illegal or even suspicious.
I think she did. She said they were wearing weapons.
