Question about Bailey’s involvement in certain plotlines — is there an in‑universe explanation?

I’m fairly new to The Rookie and currently on Season 8 Episode 1, and I’m genuinely confused about a specific writing choice. I’m hoping someone can clarify if there’s an in‑universe explanation that I’m missing.

Bailey is a firefighter/paramedic with the LAFD, so her presence in Prague — especially participating in law‑enforcement‑related activities — feels extremely unrealistic to me. I’m not criticizing the character herself, but the writing decision to place a municipal firefighter in an international fugitive operation seems odd.

From a procedural standpoint, firefighters don’t carry firearms, don’t get deputized for overseas missions, and don’t accompany law enforcement teams on tactical arrests. So I’m trying to understand whether the show ever explains how or why she’s involved in these situations, or if this is simply a creative choice to keep her connected to Nolan’s storyline.

I’m not trying to “hate” on any character — I just want to understand the logic behind this writing direction. If there’s context I missed, I’d appreciate someone pointing me toward it.
