Time-delayed tweets of police dispatches in Seattle

From the NYTimes this morning I learned about a new program from the Seattle Police Department: Tweets by Beat, selected, time-delayed tweets of the dispatcher's calls to officers in the field.

They read like dispatches!

The dispatches are broken up, by neighborhoods, into 51 different feeds. "The feeds," the Tweets by Beat page says, "do not include information about domestic violence calls, sexual assaults, and other certain types of crimes." (Does a person filter the dispatches suitable for tweeting, or is screening automated against a list of words or a dispatcher's code?)

The Tweets by Beat page says the posts go up one hour following the live dispatch, though I notice significantly shorter lags (from about a quarter-hour to a half-hour) when I compare the time the dispatch says the incident was reported, and how Twitter logs the subsequent tweet. See the attached screenshot.
