> Stated by whom?

Themselves.

> There's zero evidence that they intended to do anything to legislators.

You mean other than:

(1) Many of them stating their imminent or thwarted intent to do so, either by chants, in interviews, in electronic messages, or otherwise;

(2) Them bringing weapons and restraints with which to do things to legislators;

(3) Them becoming increasingly agitated and violent at the prospects of targets of violence escaping, as occurred when people were evacuated from the Speakers Lobby shortly before the breakthrough where Ashli Babbitt was shot.
