I was not there so do not know the whole story, but I have to question the legality for demand of the license/permit.
There is quite a bit of case law on this subject, but LEO that work 'security' gigs are operating under the authority of the property owner, not the government, until such time as he/she has RS of a crime being committed.
Just because he was a LEO in uniform, does not necessarily mean that he was in the lawful performance of his duties at the time he requested/demanded the license/permit, nor does it mean that the encounter was a lawful detention/seizure of his person under the 4th Amendment.
Not sure how IOWA case law stands on open carry as RS of a crime.
