I dont have faith in people to do what is right most of the time. Sorry, IMO if you pay people to report then it will start a witch hunt. History tells us that this has happened over and over again. It sows mistrust when already people in this country are disconnected. You get some disgruntled ex and next thing you know your husband is locked up for child abuse or maybe your son or even daughter. People are greedy, throw money in the mix and wow, kaboom. Shoot we are in a recession! Thats free money and the snitching would tax our already over burdened legal system.
Also to be honest a lot of people have blinders on. They are too trusting and times don't know what to look for in a SO. SO are good at hiding and lying. They manipulate family, friends, co-workers etc. into thinking they are nice and normal.
