Why would you involve law enforcement? Chase isn't doing anything illegal but you might be!
You want things on record in any way possible.
Just getting an emailed "okie dokie" back from some company executive and then doing something that could later be construed as illegal is a bad idea.
Maybe let's just agree to get a good lawyer first and follow their advice about who to talk to.
You're almost right. You have your attorney notify law enforcement. That's what he's for. He'll keep all the records and act as a buffer between you an any misunderstanding with the police.
