I thought he meant illegal aliens. I've noticed that over the last decade the number of hit and runs have skyrocketed - and yes, I believe it has to do a lot with the culture in Mexico. Probably due to the crooked police that they've experienced in the past, or something, but it seems like they flee whenever they hit someone (and it is not like they are in danger of getting deported from this 'Sanctuary State').
I was at sad memorial service for a young girl who got killed by a hit and run driver some 10-15 years ago. The driver fled to Mexico -- but to his credit, he returned a year later and took his punishment. He said his conscience would not let him get over doing what he had done - and he had just fled due to his natural instincts. He was OK. Maybe not a good driver, but a man with a conscience.
No excuse necessary. We all know mexi-crashes have skyrocketed.
