I appreciate a view from the LEO side of things, and this is not intended to be a LE bash fest.
If you go the Safe2Tell website, there is ZERO information for individuals/parents on the receiving end of a report.
In the scenario illustrated in this thread, the son is not an active shooter threat, just a responsible and non-criminal shooting sports enthusiast, like the members of this forum, who happened to make a statement to his friend about going to the range.
What would be the depth of such a report investigation?
