If you have a job that dictates the necessity of protecting cash or valuables, you may pull that off. If you get stopped by a old timer, he will understand the law you are trying to comply with, and he makes a judgment call if you are being just and prudent in your actions. If he finds fault with your actions, off you go to jail to explain it all to a judge. Attested on a Friday afternoon, possibly going to get three hots and a cot all weekend and see a judge on Monday.
If on the other hand, you get a trooper fresh out of the academy, likelihood you will go to jail and a judge decides.
In the old days, police called it the just and prudent man rule. Todays law enforcement does not so much go by it.
In the eyes of the law, you in fact have fewer rights with a CCW permit in Nebraska. However, that all depends what light that law is interpreted under.
Me personally, I am becoming less and less trustful of anything gov, and I have decided it is time to get under the CCW statutes.
In a grocery store buying groceries, and someone sees you printing (gun seen under clothes via outline) and the cops are called. You have a R rated film you are renting on terrorists, a quart of milk, a bottle of wine, a 6 pack of beer, and a bag of grapefruit. Are you better off with a CCW permit, or better off with the Just and Prudent man rule?
You own a gun store, and it is closing time. Winter, and it is dark out. You have a gun on your side, under your coat. A police officer walks up to see what you are doing. You own the store, no CCW permit, and your gun is hidden under your coat, while you were locking up. Would any officer think your actions were just and prudent?
In the last case, few officers would challenge your decision to protect your shop, and the daily receipts, with or without a concealed carry permit. .
