If I recall correctly, there is some theoretical work on complex systems seem to imply that if you quickly introduce a large factor in just about any system, the behavior tends to result, almost certainly, in a completely divergent system. Usually with a more or less complete breakdown until the introduced factor is removed. It's not entirely unlikely that these kind of system level effects, or something similar is why - well intended - efforts regularly end up "tyrannical" in nature after a while. One argument goes roughly like this: If something exists, persistently, it is likely to have one or several strong driving forces. If you apply enough counter force in a single direction you get a "buckling" behavior as soon as you completely overwhelm the principal drivers. Now the opposing forces, known to be existing from previous behavior, will be almost entirely unopposed/undamped, and together with the introduced factor come to completely dominate the system. Thus long term stability might only be achievable by small, relatively slow, iterative changes that slowly chane the often vast number of driving forces, and their opposing forces, in relative synchronicity. A wholesale prevention of crime in public places would likely be such a factor, and while I can't predict the outcome, it's almost certainly going to be disastrous. Criminal activity is driven by extremely strong forces, some of them likely related almost purely to, potentially misdirected, survival instincts.
