“Chicago has very strict gun laws and yet the highest gun related crimes”

This is a bad argument, considering anyone in Chicago can simply drive like an hour or two away to a place with completely different laws to access guns...that's the entire point of needing national gun laws, so that someone can't just drive to the next town/state to circumnavigate their own laws. Secondly, you're right: if a criminal really wants a gun, then they will obviously be willing to break laws to get one...so, why not make that as difficult as possible for them? Shouldn't we be making it as actively difficult, annoying, and disincentivizing as we can, as opposed to just...doing nothing or making it easier?
