While yes it's expensive, a can of Coke is expensive today, other states can be just as expensive and even more expensive. Your $500 figure is inflated as well since both the wife and I did everything together including costs for NJ DMV records along with overnight courier services to deliver out paperwork to the court and iirc the total was just under $700 bucks.
While "potentially puts us in danger" I agree with, find a single instance of a home being broken into, the owner threatened or harmed (in this state) due to the newspaper posting. P00f.. The posting has been required for over 100 years and without a single reported instance any danger is insignificant to our leaders.
Constitutional Carry has absolutely zero chance in Delaware at this point due to its current politics and judges. It just simply isn't going to happen. You could literally have 20,000 signatures or even 20,000 people show up at a rally and the current government would turn it down.
One also has to remember that today everything is give and take and unfortunately gun owners usually give much more then we get. Currently yeah, we pay quite a bit BUT we can carry most places and signs can be ignored. That said, if a Bill for Constitutional Carry was voted on I could see the other side adding more restrictions. Suddenly signs are legal, pubs, bars or even restaurants that serves alcohol, banks, public transportation, etc are all off limits because politicians added on more anti-gun provisions. They could even tack on a crazy mental health checkup requirement! How much are you willing to give up to gain Constitutional Carry?
Personally I'd like to see Pro groups start working on the state suppressor ban since I see them being removed from the NFA program soon. Or something like having the silly automatic knife ban removed. They are safer then folding knives and are no more dangerous. Heck, even Maryland removed their ban a few years ago.
