Basics of Forensic Sciences

Locard's Principle states when two object come into contact there will be an exchange of some sort, meaning that evidence can be left simply by the perpetrator

Speaking of evidences, there are 2 different kinds of testimonies that should be taken into account when in the courtroom setting, those two being Testimonial and physical.

Testimonial- Usually verbal and coming from a witness and offered as an account of proof detailing what happened

Physical- Otherwise known as real evidence, is any material object that has anything to do with the case, widely considered more reliable than the former.

How can we tell if evidence can be used in court?

The Frye Standard is a test given to Physical evidence, based on science, to see if the evidence can hold up in court

The Daubert Ruling on the other hand is used to determine of admissibility of a witness testimony
