Your video link shows otherwise, that he was being disruptive. Of course the Starbucks CEO buckled, he's a victim of a lynch culture where his career and future employment is in jeopardy if he does anything but what he did. And they know this, and use it to their advantage. They're trying to enforce thought control that disallows your ability to assess a situation and judge it accordingly because you must be a racist for disagreeing and your job will be at stake.
If you want to be in touch will how people really think about the situation, just go to Yahoo article's comment section where people are freely discussing, unlike CNN and other major outlets that removed comments to silence the overwhelming majority who are sick of the lynch culture. If this was true injustice, people would overwhelmingly agree, except they don't. Nobody from Hollywood is coming to the rescue. PC culture is why Trump got elected and will likely get re-elected. And no, I'm not pro-Trump, I didn't vote for him.
This incident was not going to put Starbucks in jeopardy, the same way that H&M also was not in jeopardy. The police did their job but the manager knows that their course of action was overboard, especially when what these men are being accused of happens more than likely on an hourly basis and in fact right at the very same time those men were there. I saw nothing there that warranted a police call, witnesses saw nothing that warranted a police call. We can agree to disagree.
