Insurance Scam Backfires on Scammer

Watch on YouTube

It stands to reason that those to scammers would have been in serious hot water if they had waited for the police to arrive and see the dashcam footage, but I wonder about what would have happened without the dashcam. How many times can the scammers face the police before an officer realizes they've seen these accident 'victims' before? Could one protect oneself from this kind of scam simply by being an upstanding citizen and calling the police about one's own supposed misdeed? Anyway, the dashcam obviously helped a lot here.
