You invalidate your own position. You fear something that you know very little about. These halfway houses have strict daily rules; no drugs, no alcohol, have to be working, usually have probation officers to account to, have had to have a clean record at the initial halfway house or they don't get to this one. If they get thrown out they move to, guess where, your neighborhood where they no longer have these checks and balances.
Calm your fears and go visit Sponsors and get ithe knowledge firsthand. Why, you might even decide to volunteer there and help our/your community.
