Whenever a high-profile shooting pushes gun control back into the forefront of political discussion, conservatives usually ask liberals why they were so silent when hundreds of people a year were being shot and killed in cities like Chicago, St. Paul, and Baltimore. The standard liberal comeback as far as Chicago is concerned is that, yeah, Chicago has some of the strictest gun laws in the nation, but the surrounding states don’t. All of the guns are purchased in Indiana and then brought into Chicago — so the obvious solution is to shut down gun sales in Indiana.

Rep. Alexandria Ocasio-Cortez probably thinks she’s the first person who’s thought of this argument.

“The guns and the carnage and the lawlessness unleashed by those states.” If guns are the problem, and lax gun laws are the problem, then you’d think Indiana would be the hotbed of gun violence that Chicago is. What happens to guns once they cross state lines?

Fair enough.
