Both sides....
Doing security work in everything from HUD public housing to seven figure type mansions of well known celebs & professional athletes I can tell you directly there are risks-concerns on
both sides.
These posts remind me too of a low end apt complex I worked in where a bldg engineer came into the office telling us how he just found 03/three milspec rifles,
in a unoccupied unit. 2 of the guns were loaded(chamber and magazine). If I recall, 2 of the military rifles were AKs/SKS, the other was a old Mauser style bolt action.
The owner/property manager contacted the sheriff's office and they took them into custody. No one ever asked or claimed the firearms either.
I agree with being cautious if you do in-home visits or work with the public. To keep track of employees or to use alarms or duress codes is smart.
If you are unaware with
duress codes, it's a simple word or phrase that sounds meaningless
but will inform the other party that you or someone is under duress or in immediate danger.
As a tenant or property owner(business or personal), you need to be alert to danger signs too.
To have CCTVs or security systems that can
clearly show vehicles or license tags,
is a good idea.
