BODYGUARDS, SECURITY GUARDS, AND AGENCIES: How Physical Protection Works in the Czech Republic Physical protection isn’t just about men in black suits with earpieces and sunglasses. It’s a complex system of services that play a daily role in safeguarding individuals, property, and public order. From high-profile bodyguards to warehouse security and rapid response teams from private agencies—their work is often discreet, but absolutely crucial. In the Czech Republic, hundreds of security companies employ tens of thousands of people. Although this is a private sector, they often complement or even partially substitute the work of public law enforcement—especially in property [...]

LOCKS IN DETECTIVE LITERATURE: What Every Author Must Know In detective stories, a lock plays a pivotal role—both literally and figuratively. Literally, because locked doors, sealed chests, or hidden compartments often conceal key clues that lead to solving the case. Figuratively, a lock symbolizes secrets, barriers between truth and deception, and the thin line between trust and betrayal. For both the reader and the detective, a lock represents a challenge waiting to be overcome. Therefore, if an author chooses to incorporate the motif of a lock in their narrative, it is essential not only to understand its symbolic meaning [...]

Each section includes real cases and lessons that can make a difference. Manufacturing Defects: When the Lock Fails on Its [...]

SECURING BASEMENTS, GARAGES, AND WINDOWS: Weak Spots Burglars Love Burglars don’t seek challenges. They seek weaknesses. And those are often not found at the front door, but in less obvious parts of the house – in the basement, garage, or windows. These areas are frequently overlooked, underestimated, and secured only symbolically. Yet they often conceal not only valuable items, but also a potential entry point. Home security isn’t just about a strong front door lock. It’s about mindset – being able to think like an intruder and analyze where your vulnerabilities lie. The basement, garage, and windows are not [...]

LOVE LOCKS: Romance on the Railings or a Security Problem? They appear suddenly, quietly, and with good intentions. A couple in love hangs a padlock on a bridge, railing, or gate, often with initials or a date. They throw the key into the river as a symbol of eternal love. This trend, known as “love locks,” has become a global phenomenon — from Paris to Prague. But behind this romantic gesture hides a less poetic reality. Locks add weight to structures, damage historical architecture, and in some cases, pose a real safety risk. What began as an innocent ritual has become [...]
