Until the person or persons who injured the officer (who died hours later at the hospital of his injuries) are specifically identified as Trump supporters, identified by name, and their social media posts identify their ideology, it remains unproven that the officer was killed "by Trump supporters".
The fact is, the only person who is proven to have been shot and killed in the Capitol that day is Ashli Babbitt, a 35-year old retired female air force veteran, who was UNARMED when shot by Capitol police. The other 3 who died were also identified after death as Trump supporters, but as disclosed, they died from "medical emergencies", strokes, heart attacks and died during CPR, not from injuries or gunfire.
The only violent plan proven to be "Trump supporters" so far is the plot to abduct Governor Gretchen Whitmer in Michigan, by a fringe group of Satanists who identify as Trump supporters, but clearly no Trump supporter outside their rural Michigan cult would endorse or support what they did.
EVEN IF any of the "Trump supporters" who raided the capitol building turn out to be ACTUAL Trump supporters, they are a tiny group who do not represent the overwhelming majority of Trump supporters (over 100,000 at the outside demonstrations in Washington that day, and over 74 million Trump supporters nationwide.) Who are being maliciously smeared to be "violent" despite that it is clear we overwhelmingly have enormous respect for police and the military, and for the rule of law. News reports said that of the up to 200 or so protesters who entered the Capitol building, only about 25 were involved in violent clashes with police. And they have NOT been identified, or their political affiliations revealed. Which again, I find rather suspect, after more than 48 hours now. If they were Trump supporters, their names and Twitter and Facebook posts would be all over CNN and other liberal media right now. The fact that they're not identified indicates to me it doesn't fit the narrative they want to sell. Beyond those 35 or 40, the others who entered the Capitol would only be charged with "criminal trespass" if caught.
AGAIN: Taunting officers defiantly, shouting obscenities and racial epithets at police, tricking police into chasing them so they can video-record police from multiple angles simultaneously, vandalism, taking trophies from the places they loot, and violent attacks on police, are ALL TYPICAL OF ANTIFA AND BLM, they are NOT typical of Trump supporters, Tea Party, or Republicans. And they have a history of violence under a false flag, pretending to be Trump supporters to commit violence during the 2016 campaign, as revealed ON VIDEO by Project Veritas to have been working for the Hillary Clinton campaign, paid for the violence under a "double wall" of deniability.
