When the camera pans down to Agent Harrison's shaking hand holding the gun, her finger is on the trigger. Anyone with law enforcement training on handling a sidearm would know that unless you are taking a shot, you always hold your finger alongside the barrel by the trigger to avoid accidental discharges. Even if her inexperience and nervousness caused Agent Harrison to forget this, Agent Dogget, an experienced and more than competent agent who was observant enough to see that she still had the safety on, should have alerted her to the misstep.
Agent Harrison is carrying a large handbag on the side of her body where she has her weapon.
That's a violation of tactical protocols as it would prevent her from quickly and easily drawing her firearm. Worse than that, an agent who is a stickler for protocol like Doggett would have immediately reminded her of this when it happened.
Agent Harrison is wearing heels.
While this is likely because she is significantly shorter than the other actors in the episode, it's also another violation of FBI protocol. She cannot run or move easily while wearing them.
