As long as bad people have access to transportaion, crime at all levels is possible.
This is an essential element of being risk aware.
Even the 'nicest' of neighborhoods have a higher level of home security because of this awawreness.
Those who believe living behind eight foot walls, enclosed by access controlled gates in the communities of oppulent manotony, keeps them FREE of all crime are living in the unfortuneate state of being risk oblivious. There have been a LOT of unlicenced pharmacies is exactly those locations.
One is never more secure than being surrounded by good neighbors they know, have fellowship with and share community values. That community is created, not found. That community is also destoryed by just one bad element moving in. Even then, working colaboratively, this is a short lived situation.
