The SUPREME COURT has ruled that taking video of police is a constitutional right. The girl had a constitutional right to tell other students to video Officer Slam and to video him herself.
Did she have a right to refuse the rightful order of a police officer? Seems many on here believe she did.
All of us have a right to question what appears to us to be an unlawful order from a police officer. That is why a specific protocol and procedure is used when making an arrest. Failure to follow those procedures and protocol and specified in numerous SCOTUS rulings can, and do leading to invalidating an arrest.
There is no evidence or even claim that the officer was there to make an arrest. The decision to charge the students with a crime was made after the incident. The evidence to this is the video and again, the fact that the claim of a warning of an arrest was not claimed.
There is no evidence of your claim they didn't inform her. You're saying they didn't do something you can't prove they didn't do.
You are claiming the student disregarded Officer Slam and is thus, guilty of a crime. In America even racist people like you have to live with a simple American constitutional right that demands a person, even a black teenager, is innocent until proven guilty. She nor anyone else has to prove her innocence, you and the other racist attacking her have to prove her guilt. So far no legal authority is even attempting to make the claims you are attempting to make.
