...I overheard Knudsen talking to the mayor about how dangerous it is to have the range in such close proximity to residential areas, and he was explaining that a round can easily hit someone on the Koko Head trail (stairs) or go over and hit more homes. He was explaining to the mayor that a wall needed to be built along the trail, or the range should be fully enclosed to prevent these possibilities...
 

People like Knudsen tick me off.  He's just like the people with houses near MCBH, HI,  and MCAS Miramar, CA, that complain about the noise.  Their houses were built and purchased long after the places they complain about were built.  The Koko Head Shooting Complex has been a shooting range since before 1950 (according to the website), MCBH has been a military installation since before 1939 (I was told the early 1900's by a PR person for the base), and Miramar was established in 1917.  Unless people owned their property around these places before they were built they have no right to complain.  They knew what was nearby and should have considered the risks.  If they didn't, that's their fault for not checking the surroundings before the purchase and should consider moving.  Same goes for the people hiking, pay attention to your surroundings, it may be what saves your life.  Though I've never hiked that trail, if there isn't a sign stating that there is an active shooting range below it, maybe there should be.
