The thing about listening to those tapes of officers shouting back and forth reporting all the Trump fans with guns was scary, especially the cop recording saying they had people up in trees brandishing AR15S....Newsweek, June 13, 2022:
"In April, 72-year-old Lonnie Coffman of Falkville, Alabama, was sentenced to four years in prison for bringing loaded guns, ammunition and Molotov cocktail ingredients to Washington on Jan. 6.
A statement by the Department of Justice said Coffman "also carried a loaded handgun and a loaded revolver as he walked around the area that day."
In March 2022, 49-year-old Texan Guy Reffitt, was convicted (among other charges) for being unlawfully present on Capitol grounds while possessing a firearm and transporting firearms during civil disorder.
A Department of Justice indictment from January 2021 also states that Christopher Alberts, Maryland, was found carrying a Taurus G2C semi-automatic handgun on Capitol grounds on January 6.
Off-duty Drug Enforcement Administration agent Mark Sami Ibrahim, 32, was also indicted by a grand jury for bringing a firearm within the United States Capitol and its grounds.
In an article for Newsweek, Nick Suplina and Justin Wagner of Everytown for Gun Safety said they had identified "12 individuals allegedly tied to the events of Jan. 6 who were arrested in Washington, D.C., and charged with firearms offenses."
It makes sense that capitol police didn't use their guns to stop the riot break in to the capitol now, they likely were aware of all the guns from radio traffick, and didn't want to have a shootout massacre on their hands, at the Capitol of the United States.
