The mural in the underpass – showing people from the past – was repainted a couple of years ago and covered with an anti graffiti covering.
That does not stop graffiti but it does make grafitti a little easier to remove.
A google search shows that this particular graffiti statement “Question Everything” predates most of the rest of the mural.
Euripides (Greek playwright, c. 480-406 BC) said “Question everything. Learn something. Answer nothing.”
If we know that Euripides wrote that, why is nothing being done to stop him before he offends again?
He should be ASBO-ed at the very least.
