Know why?
Because Capitol Hill and the Mall are secured six ways to Sunday. It is the seat of the US global empire. Congressmembers and high officials are common sights all around DC and they move around pretty freely. It is common to see them around town. It would seemingly be easy for extremists to find these people and intimidate of harm them, and yet this almost never happens.
That's because DC itself is highly secured, at least where the government people live and work. Congress and the Mall are a secure fortress within a secure city. There are soldiers, air defenses, snipers, and heavy surveillance everywhere.
The J6 protesters had no guns, no supplies, no secure communications, no central command. They were no match for capitol security. The police officers who allegedly died that day are not listed at "line of duty" deaths, i.e. no one says they were killed by J6 protester violence. Capitol security shot and killed an unarmed woman protester, the only death attributable to direct violence. This was also not the first time protesters had occupied the building.
I don't claim to know what actually happened on J6, but it is quite obvious that many of the media narratives about it are highly incompetent at best.
You can only lie to my face so many times before I start to question your credibility.
