| Independence Hall where the Declaration of Independence was signed in Philadelphia |
By Gregory Saville
On this July 4 Independence Day, I discovered something worth celebrating emerging from Philadelphia. And it wasn't the Declaration of Independence.
Last week, I was dealing with a failed air conditioner during a brutal heatwave. Calling an A/C technician was fascinating. He was energetic, hurried, and confident (overconfident – it turns out). He glanced at the unit and announced it was too old to repair. He didn’t test the refrigerant, didn’t run diagnostics. He jumped quickly to a simple conclusion - it likely had a Freon leak requiring a full system replacement —the going rate? Over $8,000!
That was declined.
The next day, I called in a different HVAC technician — someone calm, experienced, and focused. He listened carefully as I explained the background of the A/C issue, then got to work. In under an hour, he had diagnosed the real problem, tested the system, checked the wiring, bypassed a strange connection, and replaced the dirty filter. The result? Cool air again — and all for under $200.

He also went a step further – he pointed to a website that ships replacement filters automatically, provided some education on how to self-diagnose simple AC problems, and made sure other parts of the system were not at risk. “That way, you can prevent future problems and self-repair when necessary.”
That is mastery of tradecraft.
PRACTICING CRIME PREVENTION
It made me think, too often in CPTED, we meet the first kind of technician — fast talkers selling quick fixes at a high cost. What we need are more like the second — grounded pros who diagnose carefully, teach as they go, and work with the client, not around them.
Nowhere is the contrast between shallow fixes versus deep tradecraft more visible than in Philadelphia — between the neighborhoods of Kensington and Fairhill/St. Hugh.

| Philadelphia's Kensington neighborhood remains among the highest crime communities in the city |
Kensington is infamous — a high-crime zone marked by open-air drug markets, encampments, and a long history of short-term government crackdowns. One of the most aggressive was Operation Sunrise, a year-long police campaign launched in 1998 that promised zero-tolerance enforcement aimed at gangs and drugs. Authorities were confident (overconfident, as it turned out).
The effort made headlines. It felt bold, but it didn’t last.
Early criminology research praised Operation Sunrise and its “place-based policing” model, highlighting short-term drops in crime and minimal displacement. But later analysis challenged the no-displacement finding and warned of widespread unintended consequences. One study concluded the operation failed to sustain lower crime rates and instead produced a “generation of fugitives” and widespread collateral harm.
Today, government research concludes that Operation Sunshine’s zero-tolerance policing and hotspot crackdowns failed to deliver sustainable safety.

MASTERFUL CRAFTSMANSHIP MISSING
There’s nothing masterful about these strategies. They are the equivalent of replacing the entire HVAC system when the real problem is a dirty filter, a lack of client knowledge and no self-capacity to resolve problems.
When you leave Kensington and travel a half mile north, you arrive at Fairhill/St. Hugh, a primarily Hispanic neighborhood anchored by the vibrant El Centro de Oro commercial corridor.
In contrast to Kensington, the St. Hugh neighborhood has been growing and improving for a while and, while Fairhill has serious crime and disorder challenges similar to Kensington, there something very different happening.
It is difficult to get the full picture from stats and violent crime rates are notoriously difficult to measure, much less calculate. But by at least some estimates, the violent crime rate in Fairhill/St. Hugh is lower than in Kensington.
For example, one source claims Kensington's violent crime rate of 9.3 per 1,000 residents is 55% higher than the 5.9 rate in Fairhill/St. Hugh. Unfortunately, stats like this are bound to be imperfect and imperfect stats rarely tell the full story.

THE HACE STORY
Enter HACE, a community development corporation working in the neighborhood for over three decades. HACE was formed to combat disinvestment and preserve community culture. Their approach? Place-based strategies not limited to law enforcement. Instead, they use long-term investment, community leadership, neighborhood planning and strategies grounded in SafeGrowth.
Long before HACE adopted SafeGrowth, their results were stunning:
- Over $100 million in local investment
- More than 450 new housing units built
- 400+ vacant lots rehabbed and greened
- A community-run food distribution center
- Housing counseling programs that build generational wealth
Even more impressive, HACE now adopts SafeGrowth and crime prevention principles within their ten-year Goodlands 2025 plan — not as add-ons, but as core pillars of community design.
The neighborhood plan focuses on major areas of development activity, including housing, commercial corridor revitalization, improving the quality of life, and crime and safety.

They also train residents through SafeGrowth Livability Academies, helping locals become leaders in problem-solving, safety design, and civic engagement.
Academy classes lead local projects — clearing encampments, building safe walking trails, and working with police. Cops don’t arrest their way out of crime; communities and police build their way out, together.
PREVENTION TRADECRAFT
Masterful prevention tradecraft has a look: practical, visible, and led by the people who live there. It is grounded in self-help, local knowledge, rooted in evidence, and police are partners, not enforcers of one-size-fits-all solutions.
It’s patient work, unlikely to reveal itself to 6-month evaluations. Instead, it requires patience like slowly melting ice from frozen AC lines. Like tracing faulty wiring until the real problem is clear.
And in neighborhoods, as in AC systems, the difference between a temporary fix and a long-term solution is rarely visible at first glance — but unmistakable over time.
