I can´t imagine a private investigator out of spy films and crime novels.
There are a different sort of police systems, so why do you need a private investigator? It is really necessary?
In my point of view, we don´t need more people gossiping and I don´t want to be spied by strange people emploied by suspicious minds.
If anyone can employ a private investigator we will lost our personal privacy. Is it allowed by law?
I think that private investigators should only live in the cinema or crime novels but never in our lifes.
