I don't know if you are familiar with Agent Grusing's long career or not. But he is very highly respected because of the brilliant tactics he used in many high profile cases, to catch these killers. He personally brought down Mark Redwine, for the murder of his 11 yr old son, Dylan.
And he did so by spending a lot of time interviewing him, and slowly roasting him over the coals. He gave very organised and well thought out testimony in that recent trial, which helped get Redwine the Guilty verdict.
Grusing is also known for helping to crack open the Patrick Frazee case. He made a follow up phone call to a witness in Idaho, concerning a phone call from the murder suspect, Frazee, to a woman who was buying some of Frazee's horses in Colorado. In that routine phone call Grusing sniffed out the stink, and eventually rooted out that woman as the murder accomplice. Grusing is considered a very high level, perceptive Special Agent with a lot of success as an investigator and interrogator.
You may think that you could do a better job than Agent Grusing did. But you have not heard the entire 40 hours of interviews and you may be doing him a disservice by jumping to that conclusion.
By the way, FBI Agent Grusing spent 25 years as an #FBI Special Agent. He Investigated International Terrorism, Espionage , Bank Robberies, Behavioral Analysis, investigated kidnappings, serial murders, special jurisdiction crimes, missing persons, public corruption, and other violent crime matters. And he testified in multiple high-profile cases over decades. So I wouldn't write him off as incompetent.
