Why was this downvoted? It's completely factual. Officer Sicknick passed away from natural causes (the narrative that his head was bashed in with a fire extinguisher evaporated a couple of days ago[0]). Two of the protesters had heart attacks and one apparently had a meth overdose. The only person who was killed was shot by police. If you have evidence to the contrary, please cite it.
