Starbucks Must Redeem Itself : Why? How Come? Who Said?

Why is it that all it takes for an organization of thousands of outlets to change it's company policy is for two people who decided to challenge that companies policy for loitering?

Is this the real story behind the arrest of the two black men at Starbucks?

Do we actually know what was the real reason these two men were at the coffee shop? Did anyone ask them to explain why they didn't order anything but just sat down?

Who are these two men? Where did they come from and what was the real purpose for being there?

What did the store manager do that was in violation of company policy?

So many questions but few answers. Only accusations and demands for change.
