You took a fingerprint from a crime location and another fingerprint from your suspicious and easily contrasted them below a magnifying glass or microscope. Regrettably, fingerprints taken under distinctive situations can usually look quite distinctive- the one from the crime location is much more probably to be insufficient or marked- and contrasting them to confirm that they are similar (or distinctive) sometimes takes good knowledge. That is why forensic scientists (people who study prove gathered from crime locations) developed a trustworthy system for identical fingerprints where they viewed for between 8 and 16 different characteristics.
