As details of the elementary school shooting in Uvalde, Texas, continue to unfold, San Francisco Giants manager Gabe Kapler on Friday wrote that he is "not okay with the state of this country" and that he "felt like a coward" for not protesting "the lack of delivery on the promise of what our national anthem represents."

Kapler, in a blog post published Friday on his lifestyle brand website, said he was disappointed in himself for not making some sort of protest during the playing of the national anthem Wednesday.
