Insurance Scam Backfires On Scammer

I know it would be difficult to have the presence of mind to do at the actual time of the incident, but the thing to do as the driver, would be to NOT point out that you had your dashcam rolling, wait for the ambulance and/or cops to show up, and then casually mention that 'oh ya, I had my camera rolling this whole time! Would you like to see the footage, Mr. Officer?' Nailed.

Yep, Bruce is right, and it'll help nail both scumbags.
Keep it in mind next time around.

She should have done that. "Oh my God! Are you alright? I'll call ambulance and cops...." When they arrive BAM! Camera footage.
