I located the video of Sarah Huckabee the other day. His son David didn't remove a loaded firearm from his carry-on luggage earlier this year. John Mark and Sarah both work for the Huckabee campaign.
Why would a man use the campaign theme "family" and not have family photos proudly posted on his campaign website?
If he got the nomination they no longer could go about unrecoginised and would probably need some form of protection but until that unlike scenario he probably does want they to lead as normal a life as possible.
