Some people in the pro-Trump mob that descended upon the US Capitol on Wednesday wore MAGA hats. Others waved Confederate flags, or bedecked themselves in Army surplus gear. An especially memorable member of the insurrection went shirtless, but wore a large Viking hat covered in fur and horns. One accessory was near-ubiquitous: a raised smartphone. An astounding number of the attackers openly documented themselves and their peers, taking selfies in the rotunda, gleefully livestreaming their forced entry into the building, and smiling for cheeky photos on their way out, sometimes with trophies pilfered from Congressional offices.
