Even if so re the knife-— that would mean that after cops finally caught Gray & found the knife, they mistakenly thought it was an illegal weapon.
BUT prior to that-—Mosby said that cops were on bike patrol. They “made eye contact” with Gray. He fled and they pursued on foot to catch him. They caught him.
Cops had 0 probable cause. He wasn’t flashing his knife; he wasn’t threatening cops. Cops didn’t even say they shouted at him to stop. Gray made eye contact with them & he ran.
None of what Gray did constitutes probable cause.
That is a problem from the get-go.
But why run from the cops?
