Highway patrol steps in after Rep Hickey argued with atheist group

From the Capitol Journal, it appears that things got lively on the Capitol rotunda floor yesterday:
Talk that started out sounding friendly ended with raised voices and a lawmaker who said he was “insulted” by one of the secular humanists/freethinkers who spent several hours Friday in the Capitol Rotunda talking about their concerns.
Capital security, in the person of a state Highway Patrol trooper and a state public safety official checked in with members of the group after the legislator, Rep. Steve Hickey, R-Sioux Falls, told the officers as he was leaving that he had been insulted.
And…
Hickey said Tomlinson insulted him.
“He said I should take a high school science class. I said, ‘Are you questioning my education?’ He said yes.”
Tomlinson corroborated Hickey’s account, except that he thought the lawmaker seemed thin-skinned over the sharp exchange. “I said, ‘Educate yourself.’”
Did the highway patrol need to get involved? What are your thoughts?
