Another "innocent" drunk driver becomes a killer

Disabling her car was what I wanted to do but my wife's oldest sister said no.
My wife did e-mail her probation officer but nothing was done. Seams like they don't want to do any preventive policing.
Last night we think she slept in her car. She has been going to the hospital and claiming shes going to hurt herself and they put her in the psyc. ward for a week. Then gets out and drinks. She knows how to play the system.
