Typical crowd behavior. Ostracizing the rule breaking or otherwise non-conforming individuals serves at least two crucial purposes: reinforcing the status of the individual as a member of the group via respect for group norms and separating the offender in a dehumanizing way from the group allowing for harsher punitive measures given the stripping away of what makes the offender similar to group members.
Perhaps that could've been worded better but you get the idea. This phenomena is on display here as well as nearly any social media community. It is unfortunately always going to be as the vast majority of people are 'wired' for this behavior. Even those who reject the norms solely because they are 'norms' are tethered to the group, in an opposite fashion of course

. Still, it is depressing to see the lack of thoughtfulness or reason applied in instances where a community member has stepped outside the bounds of acceptable behavior. It is primarily those who do so, not for the purpose of being contrarian but because they are driven by deeper purpose, who give societies innovative ideas and unique ways of viewing reality.
Group-think is unfortunately an important albeit irritating social glue without which Lord knows how much or how little society would have evolved and improved during the history of our (or similar) species. I believe we would be worse off without it but I agree entirely with the sentiment KenSteele.
Now, speaking to the guy in Australia he sounds like one of the latter group-think bound types I mentioned above. Contrarian specifically for the sake of being oppositional. In short a major butt head who deserves what he gets as much as those other group-thinkers deserve their lot although methinks neither understands what they miss in being bound in such a fashion to their need for acceptance. Not that I have disdain for what is essentially a trait that most human behavior is governed by, I am just not wired that way. Acceptance is as a cool breeze; its nice when its blowing but hardly a requirement for getting things done. Now I'm just rambling about anything but the topic of this post....bye :0
As an aside I happen to agree with many of the rules in place at present restricting drone operation. As much as some really irk me, I can understand the need for better controls given the possibility of inadvertent death and destruction that could result from a drone and aircraft collision. Like most rules and regulations though I believe they go too far in restricting some aspects of UAS operation due to hype and resulting paranoia of the 'group'. There are some necessary limits placed on our hobby but not to the extent there are at present. Giving the power of right granting to government is bad business...
