Fingerprints inside of a location enough to make an arrest and convction? Citicop this is for you.?

Ok, myself and others have went through this many times before. I do understand the whole concept of probable cause, and prints inside of a vehicle that belong to a stranger could be consider as such. I am not denying that a persons prints that belong to a stranger to the victim is very suspicious. But, where I tend to differ, is that it is enough to convict that person, without first getting more evidence, ie (stolen goods, eye witness, etcc..) I even agree that a person with prior thefts or burglaries would make a great suspect and a conviction would be highly likely. Still I do not see how prints alone are enough to make a conviction. Simply placing a person at a scene, proves nothing other then they were there at one time. Not necessarily at the time of the crime. Just to arrest and charge a person with a crime because you can place them there seems a bit much. Hell anyone could be arrested for a crime if that was the fact. Citicop, you mean to tell me if you were investigating a burglary and you discover prints inside of the location, then you would arrest and charge that person, no questions asked? What type of investigation is that. If it was that easy to bring charges on a person, then a lot more people would be proven guilty just because they were at the scene. It seems that an interview would come first. If that person cannot be found or chooses not to talk, then you really have nothing. Hell someone could place anyone at a scene of a crime and commit it themselves, and frame a person. All I am saying is there has to be more evidence in my opinion to prove guilt. I am not denying that people have been locked up with such evidence, but even in those cases, there was more evidence. It was not just a case were a persons prints were found inside of a location, and a crime was committed, BAM guilty as charged. I have also read cases where that very evidence was found to be insufficent to hold a conviction. It goes both ways. Personally, I cannot see a DA, taking a case with just prints.
