Did you read Civil War II #4? She didn't get held for mild questioning, she was snatched off the street by armed shield agents pointing high powered rifles at her face. When she resisted, Captain Marvel ruffed her up then had her dragged away while she was crying. After being held for
72 hours (the legal maximum length of time you can be held in New York without being charged with a crime) and having her privacy violated by Shield
psychics, Captain Marvel was informed that Alison had done nothing illegal and must be released.
Does Captain Marvel let a little thing like the law stop her in her tracks? Neeeeeewp. Carol Marches in, accuses her of being a deep cover Hydra agent, tells her she's going to be tried (without allowing her access to legal council), and informs her that she can be held against her will indefinitely. When told she needs
proof, Carol says they'll find it later.
That right there is evil. Plain and simple. You arrest someone when you have evidence of a crime. You
do not get to detain someone
indefinitely until evidence can be provided at a later time to justify an arrest. Carol broke the law and violated Alison's civil rights. She also traumatized the woman into becoming a criminal reactionary. Carol is one of the bad guys. She's become another stupid Jack Bauer super-fascist analogue. A great hero for people not concerned about little things like the common good.
