Cities around the country are sprinkling "mini parks" and "pocket parks" throughout their communities. The publicly stated intent is to provide conveniently located places for all of their citizens to recreate.
However the unstated real purpose is to make it impossible for sex offenders to live anywhere in the city limits because the parks are located such that there is no place in the city outside the legal distance for them to stay.
If there is a similar legal distance from parks, schools, etc. only beyond which you can run a gun shop, then these cities have also made it technically illegal to get into the gun business.
The path to hell rather than being paved, is now festooned with pocket parks.
I think you have it backwards.
So a bus stop with a dwarf tree next to it becomes a pocket park?
