I don’t think many people know he is Daredevil. If it was well known, Hector might have said something, or Matt would have been removed from the case.

I don’t think that was Frank. The shooter didn’t walk like Frank. Also, the logo felt off, like it was too “clean.” Frank’s logo is always scuffed up or looks like it was just painted. The one in the episode looked like a vinyl sticker to me.
