They will cure the sickness of cell phone voyeurism, but only if practiced by significant numbers of voyeurs in a variety of settings. In time, and it may take a few months, public cell phone use will decrease to minimal levels for the simple reason that cell phone users will be most unwilling to make calls in public. And our perverse addiction will be cured. The cure is in the elimination of the behavior that causes the voyeurism, the elimination of public cell phone use. Once the cause has been eliminated, we must then hope that our voyeurism, having been activated and enjoyed, remains under control and doesn't break out in some other set of circumstances.
Recidivism is a concern.
Control will be difficult. Having had a taste of the pleasures of evil, it will not be easy to keep our desires under control. But we must work at staying chaste. We must force ourselves to stay on the sidewalks of life, no matter how attractive the windows might be. And we must be ever vigilant and on the offensive if anyone does dare expose his or her cell phone in public.
