Councils need to raise money one way or another. If they raise less from car parking fines we'll have to pay it somewhere else. I'm quite happy that it's raised from people who park illegally/inconsiderately.
Obviously there's a problem if fines are issued where parking wasn't illegal, but there is an appeals process and the cameras help to prove whether that was the case (rather than just a traffic warden's word)
IMO this is a mad announcement with the election in mind, which won't be as popular as Pickles thinks. People who park inconsiderately are loud noisy arses who make a big fuss, but the majority park sensibly so are completely unaffected by the cameras.
