 This new Strike Force designation allowed the operation to take advantage of sophisticated surveillance techniques such as federal wiretaps, which would require court orders and interaction from Justice Department officials in Washington, D.C. since federal law requires certain individuals to review evidence and certify the necessity of such techniques.The dealers involved became concerned as months went by and the same individuals they reported to ATF as suspected straw purchasers returned and repeatedly bought identical weapons.As they later told the DOJ OIG, their previous experience was that after they reported a suspected straw to ATF, they did not see the straw again unless subpoenaed to testify against the straw at trial.
