You'll all be pleased that after thinking about this, I now have an opinion (hang out the bunting, start waving flags).
I think that the amount of police time (as originally reported) was way over the top. If I lived in the local area and had, say, been burgled - I'd be furiousthat the police were spending time on this rather than more serious issues.
However, on the other hand, as Gromit posted yesterday, fellas - if you were walking down the street, and some complete stranger (another bloke) grabbed your butt - wouldn't you mete out some 'response'?
