plot explanation - Why were some emotional displays tolerated in Equilibrium?

When Brandt captures Preston he shouts to witnesses about how the cleric has been caught etc which seems to be a clear case of pride.

Also, I seem to remember when Preston is being interviewed and is asked about the best way to get a cleric's weapon off him Brandt smiles as he answers, clearly happy with himself.

If emotions are illegal then why are these tolerated?
