Discuss the reliability of the analytical sciences in the courtroom.
Verdich [7]

Analytical sciences are subject to the subjectivity of analysis and hence proved in courtroom on case to case basis.

Explanation:

Analytical branches of the sciences are the ones in which analytics define what propositions are true or not and not based on proving of theories or hypothesis.

This gives the work a subjective edge in that it is not completely based in proof as it cannot be.

Analysis by the virtue of the process has certain scope for human error in it thus the court proceedings do consider analytics as evidence but as a subject to human error and bias from the side of the analyst analyzing the data.
