We don't need speed. We don't need Hollywood concepts of how to be.
Lawlessness results in hasty decision-making and rushed conclusions which often result in mistakes. The ruthlessness of a fast bullet is seldom stopped from causing destruction in haste. The sword of justice is slow to swing, but the aim is true. I would rather be in the presence of one who knows where he is and knows when to act than in the vicinity of someone who doesn't and acts without having 100% certainty.
