The ACLU says that you are wrong...
"Whatever you do, keep your cooldont run away and dont insult the officer. If you ignore the officers request to stop or if you become combative with the officer, you can be arrested."
Did they detain him? Did they ask him to stop before he ran?
This story says they made eye contact and he ran, implying that he ran before any order was directed at him. It does not say they recognized him as a known felon or a known wanted man and wanted to do a parole check or had any reasonable suspicion to stop him. What reason, other than him running, did they have to chase him?
