Were there only a total of "four or five" protesters there or was it just that of an unnamed number of protesters, a subgroup of "four or five" scattered when the horse swung near? The author isn't clear. The article admits the group was small, which is a surprise given the media usually inflates the numbers of lefty protesters whenever possible. And the article only names four : Tina Richards, Adam Kokesh, Ian Thompson, and Brian Becker... so it does make a person wonder if ANSWER can only turn out "four or five" people for a "press conference" these days.
There only seems to be evidence of four, so maybe the author did inflate the number of lefties a bit... ;-D
