I'd give it two weeks, unless BW and the Councils work with the police on this. If it doesn't work because, like Borge Gush and Bony Liar, there is no planning about what to do after the war, then it will be another huge waste of BW and taxpayers money. I know which I'd put my money on.
What we found most offensive around the BCN was the tags on signage. Now if BW invested in signs that had anti-paint surfaces, preferably with a chemical reaction that tagged the perpetrators, I would call that money well spent.
