This could be considered a lip-service, as outside of his noble public persona, he is a proud and boisterous career politician that displays a certain amount of pompousness and sarcasm, as well as impatience, intolerance and disregard towards his inferiors.
This was a partial reason for creating the Mammal Inclusion Initiative, as creating opportunities for prey meant winning the favor among the majority of Zootopia.
When predator mammals start going savage, Lionheart takes the issue of solving the problem into his own hands by ordering a team of elite wolf guards to capture those gone savage and keep them imprisoned until a cure can be found, purposefully keeping the entire situation under wraps as a means to avoid civil unrest, an illegal practice.
Furthermore, his success can be attributed to his affirmative-action styled policies and espousing equality.
Though he is truthful in this regard, this probably indicates that he sees no harm in doing something illegal if it's for the sake of something he values.
Lionheart first appears during the graduation ceremony of Judy Hopps from the Zootopia Police Academy, praising her as his first police officer to be a rabbit.
Lionheart is willing to do whatever it takes to keep city life running smoothly, coining the phrase which Judy Hopps lives by: "In Zootopia, anyone can be anything", and enacting the Mammal Inclusion Initiative, an act which provides all animals with high-ranking opportunities to ensure equality among the predator and prey citizens.
