I don't care who is broadcasting the race. I don't think there is any need to be broadcasting the radio traffic between the crew chief and the rest of the team when a situation like this takes place...especially when somebody has a foul mouth like Knaus has....or....put a time delay between the actual statement and maybe a 20 second delay to air it so they can hear if it is safe to air it.
My kids had taken naps on Sunday because they wanted to stay up and watch the race. As a father, I don't use that kind of language as I don't want my kids using that language either. There are plenty of other words in the english language that could have been used that would not have been swears and I would not be saying to my kids that I don't want to ever hear you using those nasty words. My daughter then said "Daddy, you should do to him what you do to us when we swear, wash his mouth out with soap...and my son added and use that really disgusting Irish Spring stuff."
I will say it works, they don't swear in front of me or their mother anymore.
