"Running from the police is reasonable suspicion to pursue, stop and detain (and even handcuff) someone, according to the supreme court. "

Not so. Even refusing to speak to an officer and walking/running away...absent some OTHER reasonable suspicion...cannot be used to ascribe "reasonable suspicion" to detain.

And it can never be used as reasonable CAUSE for arrest.

I didn’t say it made arrest proper. Freddie Gray was a convicted felon on supervised probation. He was required to comply with police as a condition of his probation.

He fled upon seeing police.

The police had reasonable suspicion to stop and detain him.

I should have clarified, running from the police in a high crime area is reasonable suspicion. it's a "totality of circumstances" thing.
