Justin Bieber led a one man boy protest in Chicago this afternoon -- donning a custom-made t-shirt to send a message about the Twitter-related arrest of his manager Scott "Scooter" Braun.
As we previously reported, Scooter turned himself in this morning over an incident at a mall last year -- in which he allegedly refused to post a Tweet informing crazed Bieberettes that a concert had been canceled.
Braun pled not guilty.
