Exercising your right to remain silent and having an attorney represent you does not constitute a legal refusal to cooperate. Any attorney worth their salt is going to advise their client not to say a thing and contact the authorities.
As in: "His attorney Mike Caffery tells News 4, "The police are doing what they have to do, and I'm doing my part to cooperate as much as I can, but also to protect my clients rights as I would do for any client. Marshawn Lynch isn't going anywhere, everyone knows where he is, they know where he is every day. They're taking some time to collect the evidence that's necessary to proceed. They wanna get it right."
That sounds about right.
