In the context of recent events regarding terror threat levels etc ; what could you do if you felt that you had found a frequency or a pager message that may be nefarious? (I have not)
I thought about this for a while and wondered if these are monitored by known scanners in each area that may have a blind eye turned to them, or is it the case that by the time is on the air they are known to the authorities already?
-purely hypothetical of course.
