My son was arrested and he wet his pants because the cops didn't let him use the bathroom?

Do you realize that four counts of vehicular manslaughter means he killed four people with his car? I think he violated much more. You need to find the families of the people that he killed and offer your apologies and support. Don't worry about your son, he made an adult choice, and now has to face it as an adult. Mommy can't save him anymore.
