 Two Investigation Methods

Officers use only two methods while investigating a Human Trafficking case.

1. Evidence-Based

  • Collect Corroborating evidence and corroborating witness statements.
  • Strong Fact Pattern

2. Opinion Based (Most common)

  • Exculpatory Evidence Disappears
  • Exculpatory leads are ignored
  • Weak Fact Pattern
  • Incomplete investigation
  • Focus on finding Guilt and not the truth.
  • Linkage Blindness

“Prostitution is like a drug, if you don’t treat it, guess what, you're going right back to it. Why? Because the money's fast and the lifestyle is attractive. Girls on the track you get to talk to your wifey’s and hoe-socializing. The people, the environment, in the hotels getting high and partying and having a good time”

All prostitution is Human Trafficking

Minors prostitutes are all victims of Trafficking

The pimp caused the female to prostitute

Anything the pimp does is controlling the prostitute

All prostitutes are victims

Females do not have the ability to make their own decisions to become a prostitute

In 2013 the U.S.D.O.J. starting offering grant money to local Law enforcement for the enforcement of Human Trafficking.

The U.S.D.O.J. has a 58-page grant agreement local L.E. must sign to start getting the grant money. Part of the money is then distributed to the local Prosecutor's office (this is known as a sub-grantee)

Once the LE agency accepts the money (this includes all sub-grantees) the accepting agency must comply with the contract. The grant contract for all LE in the United Stated states the L.E. agency must enforce the Human Trafficking laws according to the federal law, which states all pimping of minors shall be prosecuted as human trafficking regardless of state laws.

This grant takes away all discretion from local L.E. and prosecutors from how to charge a criminal defendant.
