Aside from lecturing Bill about obeying the law, especially if he wanted to remain on the team, Wooden told him something that hadn't occurred to him -- that protesting in such a manner could've killed people. Ambulances in a hurry to get to UCLA med. center might've been caught in that logjam that Walton and his hippie comrades created. ...among other scenarios. There are ways to protest that don't involve putting the public at risk.
The lightbulb finally went on in Walton's stoned brain.
Good story, and thanks.
