It's not a question, it's a category of responders to a different question. So, read it like this, "of the people who answered that they believe there was enough fraud to affect the election results, how many agreed with storming the Capitol?"
No. This isn't a traffic stop. This isn't a protest in a park or city street. This was a mob storming the seat of government. This was a mob that, leading up to these events, had been broadcasting their intention to execute "traitors," including many members of Congress. This was a barricaded line where the mob knew that cops* were pointing there weapons at. These were cops* who were outnumbered and had apparently did not have the capacity to detain the members of the mob. (If they did have that capacity, then not detaining them was the bigger failure.)
*I use "cops", but I don't think they were there for law enforcement. They were there to protect.
