From Graver:

In what may be this year’s most exemplary demonstration of irony, a protester participating in anti-police demonstrations in Ferguson Missouri begins to suffer from a heart-attack. Her family, standing opposite from police at what could be considered the ‘battle-line’ of the protest, rushes her to the Police asking for someone to “just get her,” and that “she needs help.”

The police officers predictably see this sudden rush towards them as an act of aggression and deploy a small amount of gas in the area to discourage protesters from advancing any further. The police can then be heard telling the protesters that they “will get her,” but the protesters need to back up.
