According to Catholics, is it lawful for a president's security team to search and frisk their church leaders?

A Catholic Diocese in a certain locality in my country invited the president to oversee the ordination of a certain episcopal rank, I was shocked to see the security team of the president lining up all episcopal authorities clothed in their service robes to frisk and search them to see if they posed any security threat to the president. This exercise shows that the president and his team do not trust the Catholic Church leadership, why would the Catholic Church allow the public image and trust of their Church to be damaged this way for it would have been better if this leader didn't visit the church foe Christ and the Church is above all men including governments?
