> There were no guns

Yes there were. Three examples of people charged:

> Lonnie Coffman of Alabama: Police found multiple firearms and weapons in Coffman’s possession. Coffman’s truck, which he had parked in the vicinity of the Capitol on the morning of Jan. 6, was packed with weaponry including a handgun, a rifle and a shotgun, each loaded, according to court documents. In addition, the truck held hundreds of rounds of ammunition, several large-capacity ammunition feeding devices, a crossbow with bolts, machetes, camouflage smoke devices, a stun gun and 11 Molotov cocktails. […]

> Guy Reffitt of Texas: Reffitt was charged with bringing a handgun onto Capitol grounds. Court documents showed that Reffitt, reported in court documents to be a member of the militia group Three Percenters, told his family he brought his gun with him and that he and others "stormed the Capitol."

> Christopher Michael Alberts of Maryland: Alberts brought his handgun onto Capitol grounds. An officer saw that Alberts had a gun on his hip and alerted fellow officers. When Alberts tried to flee, officers detained him and recovered the loaded handgun along with a separate magazine.

Another:

> According to court documents, Alberts was arrested after he tried to flee police officers while leaving the Capitol grounds. Investigators said that three officers tackled him and found he was carrying a loaded 9mm handgun, 25 rounds of ammunition, a gas mask, pocket-knife, first aid kit and one military meal.

> Alberts faces four federal charges: carrying a gun at the Capitol, unlawful entry onto restricted grounds, carrying a gun without a license, and possessing a large capacity ammunition feeding device. Alberts' lawyer declined to comment on the charges.

From an actual court filing:

> Based on the foregoing, I submit that there is probable cause to believe that MEREDITH violated 18 U.S.C. § 875(c), which makes it a crime to transmit in interstate commerce any communication containing any threat to kidnap any person or any threat to injure the person of another. There is also probable cause to believe that MEREDITH violated 7 D.C. Code § 2502.01(a) and 2506.01(a)(3) , which make it a crime to possess a firearm in Washington, DC without being the holder of a valid registration certificate, and to possess ammunition unless it is for a firearm that is property registered.

> there was no centralized organization to indicate an insurrection

No centralized organization is needed. From case law (in an insurance case of all things):

> The district court held that the word insurrection means '(1) a violent uprising by a group or movement (2) acting for the specific purpose of overthrowing the constituted government and seizing its powers.' 368 F. Supp. at 1124.
