Who decides to "just close the Anchorage-Kenai road" on a busy weekend while thousands of cars stack up so that we can accurately diagram the accident scene?

If I slipped on the steps of APD or AST headquarters this winter, could we "lock down" the building and force just the relatively few officers to spend the night inside rather than go home while I painstakingly documented the ice and sanding situation? I would only inconvenience a few hundred (compared to a few THOUSAND) folks for about the same duration. How do you suppose APD/AST would respond to that?
