Our sensesSight Taste

Why are we not aware of all the information our senses are gathering at any time?•We cannot pay attention to everything at once.•We apply a filter.•We pay attention to what is important to us.
Sometimes our brains play tricks on us.

faulty.• Our emotional state influences our
ability to see or hear what is happening around us.– Upset, happy, depressed– Anxiety, fear, etc.

Observations in Forensics
Forensic Science is the study and application of science to matters of law. “Science in the service of law”
Is the scientific study of evidence to discover the facts in a criminal or civil manner.
The word forensic is derived from the Latin “forensis” meaning forum, a public place where, in Roman times, senators and others debated and held judicial proceedings.
The term forensics and criminalistics can be used interchangeably.
