Brandon A. Perron, National Director of The Criminal Defense Investigator Training Council.
Dr. Martin Luther King Jr.
during a speech on his
moral concern and Injustice.

It was Dr. martin Luther King Jr. who coined the above quote. "Injustice Anywhere is a Threat to Justice Everywhere!" Although Dr. King was not a Defense Attorney of Defense Investigator, Dr. King understood that Injustice should never be tolerated. In other words, Justice should always prevail regardless of what sides of the Civil Rights or Criminal fence you may have been on at that particular time in American History.

Criminal Defense Investigation & Methodologies
Criminal Defense Investigation
Just the mere thought of someone committing a sex crimes or physical abuse against a child or another person sends most of us into a rage of emotion. Unfortunately, in most cases the same can be said for Law enforcement and or 1st responders on a scene. This overflow of emotion can easily prevent law enforcement from conducting a thorough and unbiased investigation

However, the person who is falsely accused of these types of crimes may never, ever be able to recover from the social stigma associated with their name and family. Even when the falsely accused is completely exonerated, the irreparable damage to ones reputation has been done. We understand the stigma that the accused might be dealing with and will work diligent to help make amends so that the healing process may begin.

Sex Crimes Investigations
Private Investigators have a multitude of seldom used investigative resources that can aid a criminal defense team in their efforts to exonerate their clients. The burden of proof lies in the hands of the prosecution, so it is up to the defense team to understand what type of evidence might be needed by the prosecution to obtain a conviction.

Astute Criminal Investigations works collaboratively with your defense team and or can recommend quality counsel to represent your defense needs. It is this team concept coupled with a multitude of investigative resources at our client's disposal that has allowed ACI to experience the type of success that our clients depend on. Sometimes it can be an "Outside the Box" type of investigative resources and or methodology that creates reasonable doubt in the minds of the jurors.

Law Enforcement has a decided advantage over the defendant because they have an opportunity to view whatever evidence and or potential evidence there might be days, week and even months before the defense is even apprised that the evidence exist during discovery. Law Enforcement has unlimited resources as well, but has limited man power and hours that can be dedicated to each case. There in lies the main area where most reasonable doubt can occur. The lack of man power and dedication (" sloppy police work") will usually provide the defense team with opportunity to obtain the evidence needed to exonerate their client.
