A known offender found in a drug infested area taking off running (or on his bicycle) at the sight of police is not probable cause?
I couldn't care less that some progressive judge ruled that fleeing is not a crime. If I did the same, would they have let me be? I don't think so!
How did they know him to be a known offender? I admit he had a rap sheet longer than my arm but had any of the officer on the scene ever arrested him before? Or was it just a case of "he ran so he must have done something"?
