However automation will allow everyone claiming this sort of beenfit on insurance to be automatically followed, evidence automatically gathered, and perhaps a minimum wage flunky in India to give it a once over before the automated summons is sent.

The cheat will be caught far sooner, and the PI will be out of a job.

Of course those who aren't cheating will also be caught, as the cameras identify people who look very similar, and the courts listen to how the camera has a 1 in a million chance of being wrong (therefore will identify 350 people in the US as being the same person).

It's DNA evidence problems all over again.
