Criminal investigation has roots as far back as c. 1700 BC in the writings of the Code of Hammurabi.  In the code it is suggested that both the accuser and accused had the right to present evidence they collected.   

Around 1250 AD in England it was recorded that the constable was to "...record matters of fact, not matters of judgment and law.

Our courts are set up as an adversarial system of justice. 
(of a trial or legal procedure) in which the parties in a dispute have the responsibility for finding and presenting evidence.
"equality between prosecution and defense is essential in an adversarial system of justice"

We investigate for our Client leaving no stone unturned.
