Steph would probably offer to spar if she thought it'd help Laura feel better, even though it'd most likely end badly for Steph.

She follows Laura up the fire escape, letting her take her time to get her thoughts together to answer the question. Her own opinions of it are pretty simple: it's awful and if she could do something about it, she would.

"Oh," her eyes widen and then narrow in anger, hands clenched into fists at her sides, from the reaction it's clear she wasn't aware of that little tidbit, "They-- but-- They can't do that."

Obviously they can, but Steph is shocked enough to have a bit of a childish reaction. That's not a justice system.
