Saw that same snippet in CO statesman.

So here is a question for you: 5000 people line up to tell you something and you listen to the first 500. Have the voices of those 500 been amplified 10x by the crowd so effectively everyone was heard?

If pressed that is what was meant by "everyone was heard." Not literally heard but point was made. The sheriffs did this well, few speakers but all standing and speaking with that one voice.

Now whether the voices were actually heard over the fascinating angry birds games is open to debate.
