You may not know it but there are dozens of instances in Australia - and across the world - in which people who hit and kill or seriously injure someone and then leave the scene get off with a slap on the wrist. One person leading the push for change is Jeynelle Dean-Hayes. Her son Tyler Dean was killed in a hit and run. The person responsible was acquitted. Tears for Tyler - about Tyler Dean and other victims - will be released on September 18. If you want to help change laws so that people who use a vehicle as a weapon are given a tougher sentence than a fine or a very short period behind bars you can sign this petition, purchase a copy of the book or a wristband to support the cause.
