Gun bans do not prevent crimes,they prevent citizens from defending themselves.
CT is one of those states that have "sane and reasonable" laws as a "reasonable first start". While they never promised in writing that crimes like this would be impossible in CT, it was strongly implied, and applauded.
So if CT is so far along, and already took that "first step", what is their their "sane and reasonable" second step? Can they provide measurable metrics that we can use to evaluate their success? If they have third and fourth steps ready, why not announce and implement them now, rather than endangering innocent people by holding back?
A crisis occurs. It can't be allowed to go to waste, so roll out all the old, tired, and phony buzzwords, pretend they're brilliant new ideas, and hope nobody looks back at the previous example of them dancing on the bodies of innocent people.
