I hate to break it to you, but Officer Sicknick died from a stroke that stemmed from a blood clot (according to his brother). He died the day AFTER the Capitol breach. The New York Times made up the story about him being beaten to death by a fire extinguisher. It was a media hoax to help Democrats.
Sicknick’s brother, Ken Sicknick, also told the non-profit news outlet ProPublica that Brian Sicknick’s family had been informed the officer had suffered a stroke resulting from a blood clot. (The term “stroke” means an event in which blood flow to the brain is interrupted, resulting in brain cell death.) Ken Sicknick also said his brother told him in a text message sent before he collapsed that he had been hit with bear spray wielded by rioters.

But are you surprised? After all, this is the Democrats MO… they lie, cheat, and literally steal their way to every victory they claim. They truly are the party of fraud.
Let’s think about this for a second… CCTV cameras cover every square inch of the Capitol Building, reporters were EVERYWHERE, hundreds of iPhone cameras were rolling… yet we can’t seem to get our hands on a SINGLE VIDEO showing the “moment Sicknick was struck in the head”. Why? Because it straight up didn’t happen.
The NY Times ran with a story they didn’t have a SINGLE SHRED OF EVIDENCE to support. And when they finally got busted for it, they quietly retracted the entire article.
