The Defuse Podcast: Where Experts Defuse Real Threats
When the threats are real and the stakes are high — what actually works?
Right now, as you're reading this, someone's watching your family, your business rivals are digging through your digital history, and a disgruntled employee knows exactly where your vulnerabilities are. While you're focused on your day job, they're building a plan.
This podcast exists because ignoring threats doesn't make them disappear.
I'm Philip Grindell — former Scotland Yard detective, behavioural threat specialist, and author of Personal Threat Management. After Jo Cox MP was murdered, I was tasked with creating Parliament's specialist threat assessment team. I've spent 35 years stopping people who wanted to hurt prominent individuals, from MPs to royalty to the ultra-wealthy.
What You'll Get From Listening
You'll recognise the warning signs everyone else misses. That "helpful" new employee asking odd questions. The photographer at three different family events. The online critic whose interest feels too personal.
You'll understand how dangerous people operate. The people planning to harm you treat you like a research project — cataloguing your habits, weaknesses, and blind spots whilst you're oblivious.
You'll know what to do when a crisis hits. Not theory — actual steps. How to control the narrative when your reputation's under attack. When to stay silent and when silence destroys you.
You'll discover what's already out there about you. Right now, strangers can map your life using tools you've never heard of.
What You'll Hear
Straight-talking conversations with ex-FBI agents who've tracked serial killers, digital investigators who can find anyone online, crisis managers who've saved billion-pound reputations, and psychologists who understand exactly how fixated individuals think.
Topics include stalking, fixated individuals, insider threats, protective intelligence, reputation management, OSINT, digital vulnerability, and crisis leadership.
These aren't interviews — they're operational briefings. Real cases, real tactics, real consequences.
Who This Is For
You must understand modern threats if you're responsible for protecting someone important (yourself, your family, or your boss). Physical violence is just one possibility. Reputation assassination, digital stalking, insider betrayal — these happen far more often and can be just as devastating.
If you're prominent enough to be a target, you already are one. The question isn't whether someone's paying attention to you — it's whether you're paying attention to them.
What Makes This Different
No corporate nonsense. I've watched too many good people get hurt because they received sanitised advice from people who'd never faced real threats. You'll get the truth, even when it's uncomfortable.
Experience that matters. I've identified planned terrorist attacks, managed stalking cases involving royalty, and helped ultra-wealthy families navigate threats they never considered. Every recommendation comes from cases where lives and reputations were on the line.
Stories that stick. Theory doesn't save lives — understanding does. Every episode includes real cases that show you what threats look like before they turn dangerous.
Because the people planning to hurt you aren't taking the day off.

Behavioural Threat Assessment – a political and commercial insight with Bill Zimmerman
Bill Zimmerman has spent over 35 years analysing and managing threats. He started out in the fledgling Threat Assessment team of the US Capital Police shortly after its creation and, having spent over 20 years there, moved into the private sector on his retirement from law enforcement, where he continues to be a leader in the field of Behavioural Threat Assessment. Despite his long career, Bill is one of the humblest men you will have the pleasure of meeting. He is a fountain of knowledge and expertise, and in this podcast, he shares some of that wisdom.
Key Points:
- Behavioural threat assessment has evolved to focus more on identifying concerning behaviours early on rather than just reacting to direct threats. This allows for more options to address issues.
- Practical threat assessment requires communication and information sharing between different protective teams and agencies that may deal with the same individuals.
- The rise of social media has made it easier for people with extreme views to find communities that validate those views, which can encourage more dangerous behaviours in some cases.
- Workplace violence and threat assessment are recognised concepts in the US, but there is no agreed terminology for these issues in the UK and Europe yet. This hinders the recognition of toxic behaviours like bullying as serious problems.
Bio:
Bill Zimmerman was assigned to the Threat Assessment Section (TAS) of the U.S. Capitol Police. The mandate of this section is to investigate threats against Members of the U.S. Congress, their families and other statutory protectees. As a TAS Investigator for over 25 years, he conducted thousands of investigations into individuals concerned with the Congressional community. He collaborated with other Government agencies, local law enforcement, private security, and members of the private sector, who were integral parts of the investigations.
As the senior investigator, his responsibilities included traveling regularly to conduct security awareness seminars for the Senate and House staff throughout the United States and protective intelligence teams for congressional leadership and other congressional events. He helped create and develop guidelines for investigations with input into procedures currently used by the TAS and other Agencies throughout the United States and Great Britain. His experience was solicited for input into developing numerous publications on threat research and risk assessment.
Today, he incorporates that knowledge and experience to help conduct violent risk assessments and assist in creating threat assessment and threat management teams.
