I took a train down to the city today. As usual, one is entertained to graffiti-littered walls all along the way to the city. Today is the first time I saw a group of graffiti writers in action. They did not seem too concerned that train travelers are actually witnessing their act. It looked like the group was taking their own sweet time to do the "job".
As a way to fight graffiti vandalism, I suggest that local councils display a phone hotline at all places where graffiti writers are prone to strike. This should be in a prominent position where passersby can see from a distance and where it is out of reach of the graffiti writer. Hopefully this will send a strong message to would-be graffiti writers and discourage them from carrying out their acts.
