When a silent alarm has been tripped, it means something is wrong but the people involved might not know about it.
The reality is, in most cases, when a silent alarm goes off, the people involved SHOULD know something wrong is happening.
In the case of a bank robbery, the robbers might not know the silent alarm has been tripped but they do know they are doing something wrong.
How many silent alarms are going off around you that you should be aware of? Is a coworker stealing from the company and are you turning the other way so as not to be involved? Have you seen someone shoplifting and done nothing about it?
Look around for the silent alarms going off around you, if you do so, you can make a difference in your world.
Have a great day!
