HAS crime in Darlington become so bad that a Rambo-style vigilante group of people have had to set up their own private police force (Echo, June 6)? I am all in favour of keeping thugs of the streets. If Sparta Security is what is needed to do it, then so be it. If the company does a good job, I am all for it.

But what sort of advert is this to people who may wish to move into Darlington?
