Tagging, it's easy to forget, is a form of theft. Anyone who tags someone else's property without their permission, whether with a magnificent mural or a crude signature, is as good as removing from their bank account the money that will be required to repair the damage.
The more self-confident taggers will proclaim their work to be art - which it certainly is - and tell you that the property owners they favour with their creations are lucky to have it, which is less certain. If so, they should be able to inform the owners in advance of their plans to receive face-to-face their grateful thanks and a box of Roses for their trouble.
Tagging as an art form is so popular that many people pay to have their properties so decorated. We once commissioned a tag on our home that a zealous council functionary painted over in a fit of anti-tagging enthusiasm.
We had quite the laugh over the phone to council about that one.
So it's surprising it has taken this long for the prospect of jailing Ross Goode, a persistently reoffending tagger with more than 800 tags to his name, to come up. That said, a jail sentence for this crime is foolish because it won't change anything and will merely reinforce a rebellious mindset.
