I agree you don’t want to compromise any security info, but this is the last, last, last, last line of defence. If it gets to that point you had several colossal fuck ups that all aligned. What happened on Jan 6 was an ad hoc defence from the scattered mess that happened to be around (and which did not actively open the doors to “protestors”).
I edited my first comment, you have FBI operations, wire tapping, infiltrations, etc. Security starts way before it gets to the Capitol grounds.
As for Trump, he’ll start the hunt way before Jan 6.
