Can I swim with great white sharks?

I would like to dive with the ocean's biggest and fiercest predatory fish; not inside a shark cage. Is it possible to do this safely? I know that if you make yourself clearly visible to a great white, they will understand that you are not a seal and will not attack you but...are they at all unpredictable? Could it possibly mistake me for a potential predator (even though the only natural predators of great whites are killer whales/orcas)? Sharks are my passion and I'd really like to befriend and interact with a great white shark.
