Its always the old bills fault 
Nah, it's the wee b'stard with the matches fault. However the Polis don't help themselves, I speak from various dealings I've had with them over the years. They do project an attitude of couldn't really care less.
They actually said to my mate who got is nose splattered (for no reason) when he was out getting nappies for his kid. "Probably won't catch the guy". Not with that attitude mate, this is despite being provided with a description and bloody fingerprints on the plastic bag he picked up to see if they was anything worth nicking. That and their parking on double yellow lines when they're on personal business...blah blah, I could go on.
I understand they have a difficult job and I don't envy it, however if you take the money you do the job, properly.
