Here's the formula.
I know that X happened in P.
Therefore X is a regular occurence in P.
X = home invasion and rape
P = Baltimore City
Despite the fact the rape rates are significantly higher in the counties than in the City, this is sufficient proof that Baltimore is THE MOST DANGEROUS CITY EVER OMGZZZ.
Thing is, I know that Red Marylanders have access to statistics that could make their point in a much more reasoned, less fallacious manner. That just isn't their style.
