Actually, in their minds they can. It's because of guns coming into the city from the surrounding towns who have "lax" laws. It's how they rationalize making their perverted view into state law and how they browbeat surrounding states, particularly Indiana, to adopt the same bizarre attitude toward guns.
And the lib lightweights won’t mention the Mexican cartel channel sending guns, drugs to Chi-land.
And that is why they don't have a drug problem - drugs are illegal everywhere. Simple logic...
