Under the new law, police will identify illegal immigrants, beginning a process that will lead to their deportation. This makes any interaction with the police dangerous for them, and effectively eliminates the police as a source of protection for them.
Suppose a crime, such as robbery, assault, or rape, is committed against an illegal immigrant. If the victim reports the crime to the police, he or she will be deported. By comparison, the perpetrator faces lesser consequences than the victim even if caught and convicted, which is rather unlikely after the victim and potential witnesses are deported, or prevented from coming forward by the threat of deportation.
It seems that when the new law goes into effect, we have free rein to do whatever we want to the wetbacks. Have fun. Just be careful not to target anybody who's here legally.
Word to the wetbacks: pack your bags, or pack heat. You're on your own now.
errr ... what about moving to another state ?
