About the show

Prominence brings risks most people never have to think about. Some involve harmful behaviour, such as stalking by a fixated follower or harassment by a former employee with a grievance. Others are less visible: the wrong hire, the pressure a family carries in private, a child growing up with a known surname, or governance that never caught up with the wealth. In each episode, Philip Grindell talks to someone who handles these issues for a living, from investigators and psychologists to recruiters, lawyers and family governance advisers. Together they look at how to prevent problems and how to address the ones that have already started. If you look after someone whose name opens doors, or the name is yours, this is for you.

Understanding Behaviour, Preventing Violence | Dr Karie Gibson

Recognising concerning behaviour is only the beginning. Understanding what it means, and deciding how to respond, is where prevention starts. In this episode of The Defuse Podcast, Philip Grindell joins Dr Karie Gibson, a psychologist, former FBI special agent and former head of the FBI’s Behavioral Threat Assessment Center, for a conversation about profiling, targeted violence and the practical work of threat management. Drawing on her experience investigating and assessing complex cases, Karie explains what profiling involves, where its limits lie, and how assumptions can lead us to overlook the behaviour that matters. They explore why mental illness alone is a poor guide to understanding violence, how grievances can develop into fixation, and what the pathway to violence can help us recognise. The conversation also covers online threats, the distinction between “hunters and howlers”, and “leakage”, when someone reveals violent thoughts or intent to others. Karie discusses why families, friends and colleagues may notice changes first, and what can stop them from raising concerns. Above all, this is a conversation about acting on an assessment. Karie shares how connection, purpose, practical support and carefully tailored interventions can help move someone away from violence. For anyone concerned about someone’s behaviour, or responsible for protecting others, this episode offers a clearer way to think about the concern and the next step. About Dr Karie Gibson Dr Karie A. Gibson is a licensed psychologist, former FBI special agent and certified FBI profiler who served as Unit Chief of the FBI’s Behavioral Analysis Unit responsible for the Behavioral Threat Assessment Center (BTAC).

The Omnipresence of Fear: Understanding Stalker Psychology with Kerry Daynes

This episode features forensic psychologist Kerry Daynes discussing her 25-year career and expertise in stalking behaviour. Kerry transitioned from advertising plans to forensic psychology after university, despite being told it was "no job for a girl." She trained through the NHS rather than the typical prison service route. Key Professional Insights: Kerry advocates for "rational compassion" - maintaining realistic risk assessments whilst treating individuals with dignity. She argues against forcing people into neat psychological categories, emphasising that everyone requires individual understanding. Stalking vs Harassment: Stalking involves deeper fixation and obsession than harassment. Stalkers gather unnecessary information and seek proximity to victims. The UK recognises five stalker types: rejected (highest violence risk), intimacy-seeking, incompetent suitors, resentful, and predatory stalkers. Risk Assessment Problems: The widely-used DASH risk assessment tool lacks scientific validity despite being standard across UK police forces. This "quick and dirty" approach fails because it attempts to assess domestic abuse, stalking, and honour-based abuse with one inadequate tool. Personal Experience: Kerry shares her own stalking experience, describing the victim's sense of "omnipresence" - feeling unsafe everywhere. Victims typically shrink their lives and experience hypervigilance, which others often dismiss as paranoia. Societal Issues: Popular culture romanticises stalking through films like Beauty and the Beast and Twilight. Social media and data oversharing have made stalking easier while creating unrealistic expectations about pursuing romantic interests. https://www.linkedin.com/in/kerry-daynes-aa8b5740/ https://www.instagram.com/kerrydaynespsychologist/?hl=en Support the show Subscribe to 'Defuse News', our weekly update of the week's events on our website .

When Crisis Hits: The Real Cost of Getting Reputation Wrong

When Crisis Hits: The Real Cost of Getting Reputation Wrong This week's Defuse Podcast featured Heather Blundell (CEO, Grayling UK) and James Clothier (Head of Crisis) discussing how reputation management has become essential protection. Key insights: Most crisis failures stem from human behaviour under pressure, not poor messaging. Female executives face different reputation attacks requiring specific strategies. Social media breaks stories before traditional media responds. Video responses are replacing written statements as authenticity matters more than polish. Heather revealed that proactive reputation management creates a competitive advantage, not just damage limitation. The conversation covers timing challenges, the importance of an external perspective, and why lawyers often make statements worse by stripping out emotion. They discuss how social media has transformed crisis response - young people get news from Snapchat, stories break on Twitter first, and video content is becoming essential. The practical advice focuses on being honest, letting the light in, and demonstrating genuine change rather than just promising to "learn lessons." Heather Blundell’s Biography: Heather is the award-winning UK CEO of Grayling, a global PR firm, responsible for 200 employees across nine offices. She has spent more than 16 years as a trusted adviser to some of the world's largest companies and prominent CEOs, guiding them through periods of significant change, disruption, and complex reputation and crisis issues. Heather is also a regular media commentator in the national media. James Clothier James is Head of Crisis at Grayling UK, responsible for leading the crisis and reputation practice, alongside the firm's corporate division. Before joining Grayling, James spent two decades in senior editorial positions at The Sun and the Daily Mail. https://grayling.com/ #ThreatIntelligence #CrisisManagement #ReputationRisk #ExecutiveProtection #CorporateSecurity #StrategicCommunications Support the show Subscribe to 'Defuse News', our weekly update of the week's events on our website .

OSINT Part 2 - The Digital Lens Into Personal Security with Jon BlakeUntitled Episode

OSINT Part 2 - The Digital Lens Into Personal Security with Jon Blake In the second part, Philip and Jon delve deeper into technical aspects of OSINT and digital security: - VPNs (Virtual Private Networks): They discuss how VPNs create secure, encrypted connections through virtual "tunnels" and their benefits for security, particularly when using public Wi-Fi. They also address limitations, including potential impacts on speed and some websites detecting and blocking VPN access. - The security risks of public Wi-Fi networks, with Jon recommending always using a VPN when connecting to hotel, airport, or other public networks. - Using OSINT for due diligence, including understanding a person's "digital footprint" (information they know about and control) versus their "digital shadow" (information they may not be aware of, like data breaches). - Techniques for conducting effective searches, including using Google Advanced Search rather than basic searches, and applying filters strategically. - The challenges of images online, including metadata that can reveal sensitive information like location data, and the use of reverse image search technology. - The emerging role of AI and automation in OSINT investigations, with Jon cautioning that while AI tools can be helpful, they need human verification and should be used carefully. - Deep fakes and their security implications, particularly for high-profile individuals and organizations, with Jon emphasizing the need for verification processes and code words as potential safeguards. The podcast concludes with Jon highlighting his company's training programs and customizable "cyber investigator pathway" courses available through Cyber Ops Global.

OSINT Part 1 - The Digital Lens Into Personal Security with Jon Blake

OSINT Part 1 - The Digital Lens Into Personal Security with Jon Blake In the first part of this podcast, Philip Grindell interviews Jon Blake, a former Metropolitan Police Detective who has become an expert in Open Source Intelligence (OSINT). They discuss: - Jon's background as a career detective who moved into cyber investigations, worked in covert operations, and eventually became a national internet investigation coordinator before entering the private sector in 2015. What OSINT is: Open-source intelligence refers to gathering publicly available information and processing it for reliability and assessment. Jon notes that in policing, they've moved away from the term "OSINT" to "triple I" (internet investigation and intelligence). - The difference between the surface web (indexed by search engines), the deep web (content not indexed by search engines, such as commercial databases), and the dark web (accessible only through specific tools like Tor). - The distinction between open source (publicly available information) and closed source (information from private systems). - The importance of treating digital evidence properly, including creating audit trails, capturing evidence methodically, and preserving digital material to maintain its integrity. - How investigators must approach OSINT with the mindset that any information gathered could potentially become evidence, so proper documentation and verification are essential. The experts emphasise that OSINT is a powerful investigation tool but should be part of a comprehensive approach rather than relied upon exclusively.
