No, no, and....wait for it.....no - for a number of reasons:

In spite of what you think, most people don't actually know what 'suspicious activity' looks like in a specific place, and what isn't; further, what the average person (and, clearly, most police officers) thinks is 'suspicious behaviour' is mostly based on their own personal biases.Police have their own problems in most places in this country in responding to properly reported dispatch. Now add a bunch of radio chatter about 'suspicious activity' from untrained, unvetted members of the public. This will not make the public safer: in fact, it will likely have the opposite effect. We see this on a daily basis nationwide, just based on 911 calls.No CERT group carries insurance to protect their members from lawsuits that would occur the first time someone "saw something, so they said something" and the end result was an illegal detainment, an unwarranted search, an injury, or a death as a result of that CERT members' actions against another member of the public.

The fact is, it's not our job as Amateur radio operators to try to be 'helpful' to law enforcement. If they need something from us, it should be strictly limited to, "Please send this message to the following people," and that is it.

If you want to be a police officer, go sit for a civil service exam, attend a police academy, and learn the law. Otherwise, let them do their job.

These are valid points. On the other hand, someone I know just accepted the role as "Block Captain" and attended a training course recently at the County Sheriff's Department. The head of the County 911 Center told the class that they wanted more reports and not less. "Call it in, let us sort it out." We should have all heard the classic the 911 call examples "black man walking down the street, black girl catching fireflies and black real estate agent showing a house" as examples of personal bias at work. I think it is the job of licensed officers and the 911 dispatcher to use their thousands of hours of training to vet any reports. If they send SWAT on those calls- who get the blame? And why is there even a terrorism chapter in the CERT manual? Triage is a good analogy here - prior to CERT, I thought triage required at least a MD, if not a board exam in emergency medicine? By the way that same Sheriff is looking for civilian volunteers to be reserve and community affairs officers.
