Code Red works (sort of)

I remember signing up for this new feature offered by the City of Duncanville to its residences a few years back called “Code Red.” There was a link right on the duncanville.com website so I figured yeah, what the heck.
Never got a confirmation e-mail back and never heard anything else about it.
Until this week.
Wednesday I get a phone message saying there were 2 armed gunmen loose in my neighborhood.
And I was in Miami.
Two armed gunmen on the loose? Where, exactly? Why?
The Code Red system automatically dialed my registered phone number (and those of my neighbors) and left a generic warning message. But that was all.
A cancellation message followed some time later but still no information.
Had they been caught? Gunned down? Did they take hostages? Shoot their way out in a horrific gun battle? Make any inappropriate gestures towards news cameras? Order takeout?
Dang. All this Code Red call did was raise my curiosity.
Dang.
