incompetence does not overwrite intent. They were gathered there and committed political violence for a specific reason - to halt the peaceful transfer of power to the next administration.
And they left after a lockdown was already in-force and they were removed from the premises by force.
What was the intent? Do you know or are you assuming?
I think if their goal was to actually take control of the capitol things would have gone much differently. I find it hard to believe this was anything but a protest.
Five, actually. Officer Brian Sicknick died as a result of wounds suffered during the conflict [1]. Details beyond that are still hard to find. This after Giuliani demanded "trial by combat" from the gathered mob. Hard to believe he will face justice though, given that Trump plans to pardon everybody and their mother.
