Because she thinks it's her job. A cop always puts their life on the line for the sake of others.
She believes her life is less valuable than those she protects. In this case, Unlike Tenzin and Su, who have responsibilities to their nation/city and families waiting for them, she feels she has little at stake aside from her life and job.

That took a dark turn but considering her traumas and all, it kinda makes sense. (At least for me.)
*headcanon(for LinZin shippers): that "first glance" was her wanting to say "I love you" to Tenzin
