"If You See Something, Say Something™

I am reading this article "If You See Something, Say Something™ here (http://www.dhs.gov/see-something-say-something).
Reporting Suspicious Activity
To report suspicious activity, contact your local law enforcement agency. Describe specifically what you observed, including:
Who or what you saw;
When you saw it;
Where it occurred; and
Why it's suspicious.
If there is an emergency,
call 9–1–1.
Do not report suspicious activity through this website or the campaign email address. Report suspicious activity to local law enforcement. Please use this site to inquire about partnerships with the DHS "If You See Something, Say Something™" campaign only.
