You missed out the bit where I explained the context and object of an 'emotional' outburst. I removed 'breakdown' too. You're doing what I saw as emphasising just one part of what happened for the biggest headline. But yes, somewhat pedantically, you're right to describe both anger and frustration as emotional. The point is the 'emotional breakdown' is used originally (in press reports) as an attempt to enflame a not so enflamed event. Footage of an event will often lend itself to various interpretations from different viewers.
