I'm a bit late to this thread and the spotlight may be off, but if you want to prevent people from thinking the worst of your establishement, "no comment" is not the path to take. That will only reinforce to those on the other side that something is being hidden, or the establishment feels it must cover it's six to cover up acts or omissions. The WORST thing the establishment can do, from a PR perspective, is have itself go on record for "no comment", not respond to press inquiries at all, or the absolute worst, lie.
If you are asked a question, there is nothing that says you must answer it directly. For example, if asked "Do you feel the range is responsible for what happened?" say something positive, like "This range has been in business for XX years and serves XXXX customers each year. Our hearts go out to the family of the victim of this personal tragedy. It's hard to understand how someone can reach a point that they feel the only way out is to end their life."
In this manner, all they have are positive statements to choose from. If they want to slant their story to paint guns and ranges in a bad light, they'll have to make it up on their own.
