Connecticut has very likely created tens of thousands of newly minted criminals; 20-100k at least

45. This just in: people often blow off pointless, seldom-enforced laws.

Registration is largely security theater, particularly when limited to a class of weapons that doesn't commonly appear in crime. That general uselessness alone will make it a low priority with law enforcement. Attempting to enact draconian penalties will only bolster the arguments of those who assert that registration is a gateway to eventual prohibition.

The question of whether or not to comply with registration edicts is presently moot to me: I don't live in a state that registers firearms, nor is such legislation likely to pass here in Oregon; even liberal-leaning Western states tend to have fewer firearms restrictions. I'd certainly oppose such a proposals here (although I actively support other measures, such as universal background checks), as I do all pointless, feel-good legislation.
