In their slight defense, they got blindsided into a response when RIttenhouse wore a branded T shirt in the photo. If his lawyer knew anything at all about optics, he would have told him not to wear anything distracting that would take away from the message - he made bail, period. There's no reason to throw chum in the water and distract from that message.
I actually thought for a second that Rittenhouse was sponsored in some way by Black Rifle, so it's a reasonable question to ask. Their reply may come across as Judas-like, but taken to the essentials it is pretty neutral.
What disturbs me more is that Rittenhouse has a lawyer who didn't notice this and be more proactive. Also in case you're wondering that's his lawyer on the left, the one in the sweatshirt LARPing as his uncle or something. Lawyers should look like lawyers in any public appearances, period - wear a goddamned suit. He did this on Fox shortly after the event too - open collared shirt and no jacket. Yes, this matters - he wouldn't be allowed to wear that casual crap in court, and he should know enough not to wear it in the court of public opinion if he wants to be taken seriously.
