Tom DeLay also famously gave his best smile for his mugshot.
On a practical basis it makes much more sense than to have a mugshot with an “I’m guilty and got caught” face on.
Funny you should mention him I know the story of Tom delays amazing smile and that photo I was the product of an expensive consultation with the top political consultant who told him:
“you should picture being at a Fourth of July picnic at a beach; you just won some amazing prize and you are 18 years old —make THAT kind of smile” he was told.
I have one arrest to my name and for my shot I remembered the advice of that political consultant.
I did the same thing.
Doesn’t look guilty to me.
