...is to shame them.
In the UK (specifically the counties of Avon and Somerset), the police have started putting hoax or imbecilic '999' calls (that's the British equivalent of '911' calls) onto YouTube. Like this one individual that called to tell police that a (quite common) gray squirrel was near the M32 motorway without any hazelnut trees nearby.
Or the woman that lost her glasses, so she can't peel her potatoes.
More below the fold...
Have you ever noticed how quite a lot of people will do things without thinking about it, but hate it when the media pays attention to them as a result? In the instance I'm imagining, I'm thinking of when a suspect has been caught red-handed and is emerging from the police car on your local evening news. They'll cover their face with their clothes, paper, whatever they can to stop their self being known as the person that did wrong.
Why? Shame. They're ashamed. Not of what they've done maybe, perhaps only because their grandmother might be watching, but shame nevertheless.
It pains me to say it, but shame seems to be the only deterrent some people understand. So if we can show people how their lack of thought for others is detrimental to the well-being of us all, especially (with the British example) if their actions may have prevented a real life-and-death call from being answered in time, I see nothing wrong with using YouTube for this purpose.
But I'm interested in hearing what others have to say. Where would you draw the line at acceptable and non-acceptable?
