Right now shoplifters have the advantage. That has many negative effects (stores closing, merchandise being locked up). It's not the Torment Nexus to make life more difficult for them.
Yes, I would not feel that it was the Torment Nexus if I was mistakenly identified as a shoplifter. It would be a hassle though. I'm willing to rely on the business incentive to reduce false positives to avoid offending customers.
