Watched part of the video. Her first name is, Jamilla. She is a muslim convert.
She felt that congressmen were disrespecting even demonizing muslims, so her response: send death threats.
She was previously arrested for sending death threats, and when the police showed up this time, she attacked them with a knife. The cops however brought guns to this knife fight and she's like totally dead.
Bottom line. Muslim acted like a muslim, now she's dead. No great loss. Society is safer now that another muslim is dead.
Edit to add, the police suspected her because she left her name and address on the packages.
So she's a STUPID muslim as well.
