Greetings, I'm currently a criminal justice major and would like a little more understanding on the concept of probable cause. I understand it is the standard needed to effect an arrest or to preform a search, however I was curious what is the lowest amount needed for probable cause. For example suppose you have a crime, such as an indecent A&B, where all you have is a victim's statement. There are no marks, witnesses, or other evidence that could possibly assist you. Would the statement alone be enough to effect an arrest or is more needed? I would greatly appreciate any assistance! Thanks!
