What is this country coming to???

My older sister lives in LA. So on Friday, she's driving her car, and a lady runs a stop sign, causing my sister to hit the lady's car. Now, the lady doesn't speak any English (my sister speaks fluent Spanish, however, so they can still converse) and doesn't even have a driver's license. She also has no auto insurance. My sister calls the police, but when they arrive, they refuse to make an accident report. So basically, they do nothing, when this lady is here illegally, driving without a license, and has no car insurance?!?! At the very least they should have written her a ticket and impounded the car. Or at least made an accident report! Now that is jacked up!!!
