Here's the thing people seem to be forgetting.
Bella's parents might be glowies, but they're not top-level glowies. It's not like she's Nancy Pelosi's daughter, or anything. Sure, her mom might be an ex-secret service agent, but that still isn't enough to bail her daughter out of all this shit. Besides, given from how little Bella talks about her, and how her father has custody of her, it's likely that they don't have a good relationship, and that if her mother learns about any of this shit she's not want anything to do with her, anyway.
Yeah, expecting Bella to be thrown in jail forever is retarded, but so is acting like absolutely nothing is going to happen to her just because her parents happen to be low-lower mid-tier glowies. She might not be ruined for life, but there's still a very good chance she's going to at least get some repercussions for the shit she's done.
