That phrase is commonly called a fallacy (after this, thus because of this), but you can judge this instance for yourself, with a couple of stories from KOMO-Seattle.

First, there is this story about the low morale at the Seattle Police Department.  In recent years, there has been an increase in low-level street crime, and many cases of neighborhood-dwellers who shout and jeer at police officers while they are trying to do their job.  The incidents in Ferguson, Missouri and the rise of the “Black Lives Matter” movement have led to distrust of the police, and the feeling in some communities that the police do not serve them, but are a threat.  The city government has not dealt well with the rise of homeless and drug-dealing people living in broken-down, unsightly RVs in city neighborhoods, among other things. Some neighborhoods have to hire their own private security, when the City ignores their plight.

Then, there is this story, of how one local company has responded to the conditions above.  Street Crime Forces Environmentally-conscious company to Flee Seattle.  Seattle prides itself on being very “green”, funding companies such as this one, banning those evil plastic bags and plastic straws, and building street-narrowing bike and bus lanes where automobiles are not allowed.

In these cases, Post Hoc, Ergo Propter Hoc is NOT a fallacy, but very true.
