Why?

I'm watching Cops. This woman got "pulled over" on her bike and they found a bunch of drugs in her backpack. she said she didn't know how it got there. kept claiming innocence.

the cop takes her to an interview/interrogation room and asks her. she finally admits to it, and says she lied because it's too hard to admit to this problem. she starts to cry.

why the HELL am I getting choked up for this woman?

Because I'm pregnant, and that's what we do.
