Sorry, it was a rather long quote. Here’s the evidence bit:
> investigators have now pinpointed a person seen on video of the riot who attacked several officers with bear spray, including Officer Sicknick ... and video evidence shows that the assailant discussed attacking officers with the bear spray beforehand ... F.B.I. officials homed in on the potential role of an irritant as a primary factor in his death.
The full article discusses other pieces of evidence still needed to charge, and notes:
> Given the evidence available to investigators, prosecutors could be more likely to bring charges of assaulting an officer, rather than murder...
Whether the actions were assault or murder the original comment on correlation to actions of a protestor seems within line. The followup comment, to which you replied, reframed as:
> There was 1 deceased Capitol Police Officer ... don't know cause of death ... think I recall that they were investigating a singular individual
All of which sounds accurate as of what’s known at present. Again, seems off to call out the error on the fire extinguisher but not acknowledge the FBI has narrowed down to a suspect from video.
