Clearly, you don't "got it".
Not a question of "the Left".
I asked YOU ... and YOU couldn't name a single individual.
Nor apparently could anyone in the relevant law enforcement agencies, DOJ, etc.
You're "sure" of all sorts of things ... including that Revolver publishes "blockbuster articles" ...
And while it may be true that there were some cameras present and some video was recorded, there may not be all that much that is usable, in terms of identifying individuals ... depending on what time that the attacks occurred.
Depends ... and is hard to answer without knowing exactly which specific/particular events you're referring to (date, and time that they occurred)
If you are referring to something that occurred at night, after dark, it may be for several reasons:
1. they simply don't have any in that instance (much of the stuff used to identify the domestic terrorist/insurrectionist wannabes on January 6th came from independent media largely recorded during daylight ... or the morons themselves who decided it would be really cool to livestream their own riot to the internet ...
), or
2. because any photos or footage they may have wouldn't be useful in identifying suspects (time of day, low light, bad camera angle, etc.)
