Sadly, you are spot on with your observation. A friend of mine was an investigator for an insurance company, working in Lancs. 100% of claims she investigated of this nature were from the same "demographic" as the two convicted in this case. This type of fraud has been going on for years in the Preston, Blackburn, Burnley area, where there is a very large population of this "demographic".
£13 million fraud and they get two years, one suspended. There's no justice anymore. A few months inside then they'll be straight back to their old tricks.
Should you ever be a victim, get your mobile phone out, take photographs of those involved and watch the perpetrators scatter and their claim evaporate. That was the advice my friend gave to me.
I won't say what I would do to them..................
