BACA stands for Bikers Against Child Abuse. These guys will go and make a child life better by bettering the lives of those who were affected by verbal, sexual or physical abuse. This community organization protect the kids and make friends and show them that they no longer have to fear and give them a safe friend to call. Two members of the gang is appointed to a kid should they ever need to call. They say that the children who are now part of this "gang" (yes, they even get their own jackets) are more likely to talk and testify in court. Of course, the bikers will attend court with them for support.
One kid even said that she is not afraid because her new friends are much more scarier looking than the man who hurt her. They will protect her!
