There's another possibility as well.
Think about this first, when have you ever seen C&C move as fast as they did to make a repair at the range, or anywhere else for that matter. Hell, it's taken them over two years to remodel a bathroom at Maunalua bay. Top it off with the fact that they dropped $94,000 that they didn't have. [ remember, we're running a deficit, that means the money is borrowed, or was earmarked for something else ]
Now what makes the government move that fast?
LIABILITY.
Past administrations have neglected the range for the last 30 years. All the other parks in the system have suffered, but none has been completely ignored like KHSC. Now the chickens are coming home to roost, they need to do something.
The government hates to be held responsible for anything. What if HPD can prove the bullets came from the range? What if under the guise of an "ongoing investigation" they're keeping it quiet, so that when it does come out, they can say they've "taken steps to make the range safer"? I'm not saying that's what's going on, but the possibility exists. I would hope that none of this is the case, but there it is.
As far as "Erring on the side of safety", I should hope so. What if it was your house being hit by bullets? What if it were your kids playing in the yard, how would you feel? If you lived near the range, the first conclusion, right or wrong, would be they came from the range. I know if it was me, I'd want it to stop, immediately, if not sooner.
Remember, other than people like us, that use the range and own firearms, the general public basically falls into two categories. Either they're anti gun, or they don't give a shit as long as it's not a problem for them. We as a community, because of the scrutiny we're under, need to be handling ourselves in a manner that is beyond reproach, better and cleaner than the next guy.
We're going to have to face the fact that without extensive modifications and improvements, the 200, 300, 440yd targets are gone, the steel is certainly not coming back.
If you want to start a petition, start it for funding these improvements, we'll get a lot further with it.
