At least there are no current / recent worries what might make someone want to call 911
Actually, it's an interesting question -- just what is the threshold? Suspected ebola vomit? Suspicious bag on suburban street? Seems like it would be a very easy system to game, or even to unintentionally render useless. Takes a lot of goodwill and good behavior, all around.
I took a CPR class last night, and the instructor (a firefighter in his dayjob) basically encouraged people to use 911 more, even for things about which the caller might be on the fence. "We'll sort it out. Don't call about your kid's math homework, but don't *not* call because you're not sure it's serious enough" was the gist.
I've called 911 quite a few times, or asked others to (hypothermia case, guy on railroad tracks, gun shots, more gunshots, drunk drivers, etc), now I wonder what the mean / mode is for that
There are two ways to write error-free programs; only the third one works.
