The Quest Begins
Having lived in Denver until recently, I set out on a quest to understand the patterns hidden within the city's crime data. Armed with Python and the determination of a data wizard, I dove into Denver's publicly available crime records—nearly half a million incidents spanning years of urban life.
My mission was clear: organize this chaotic sea of data in a way that could help Denver's law enforcement allocate their resources more efficiently. To predict where the shadows would fall next, I first needed to understand where they had been.
This is the chronicle of that journey—a tale of data cleaning, pattern discovery, and the hidden truths that emerge when you know where to look.
Chapter I: The Purification Ritual
Before any wizard can divine the future, they must cleanse their tools. The raw data arrived like an ancient scroll—467,928 entries across 19 mystical columns. Each offense carried an ID, constructed from incident numbers, offense codes, and extensions. Some bore precise timestamps; others spoke only in ranges, their exact moments lost to time.
I discovered anomalies lurking in the shadows: 41 entries where the last occurrence came before the first—temporal paradoxes that had to be banished. Geographical coordinates sometimes vanished for privacy, while certain dates refused to align properly. Each error was cataloged, corrected, or excised with surgical precision.
The purification complete, I filtered away traffic incidents—focusing solely on true crimes. What remained was a pristine dataset, ready to reveal its secrets.
