The "tension", and "escalating" manner, that this got to, was because of the JW's. This guy, and YES it may have been a tad forward, just was asking about wanting to ask a few questions. He was upfront about wanting to tape it and that he just had a few questions. Those 3 men, IGNORING him, unable to engage him, and literally walking away from him, like children, is what escalated it.
Give the guy a chance, THEY assumed it was going to be negative, and THEY pre-judged the situation, just as much as some are saying this guy who approached them did.
When it was clear, that they WERE cowards, and just wanted to "pretend" that there was NOT a human being in front of them, then this guy acknowledged it, and walked away. He did NOT curse them out, or call them names. Yes, its true, we as the watchers of this, probably knew he wasnt sympathetic, but THEY didnt know. Their attitude was to ignore him, pre-judge his intentions, and walk away. That is essentially what HE did too. The difference, HOWEVER, is these men have put themselves on the street TO be approached, TO present information, and TO ANSWER QUESTIONS.
