Personally, I think the '911' section needs links to Pizza Hut, Domino's and Papa John's, so that the nice folks can order a pizza at the same time they call the cops...
And before I get flamage here - I've called the cops several times since I moved to a metro area:
1) witnessed drive-by - called before last round was fired - cops showed up 20 minutes later, didn't want to get out of car - gave me a hard time, especially after I showed 'em the fired brass.
2) witnessed hit and run accident - cops showed up 20-30 minutes later. We gave 'em a tag number, and excellent description. Never did hear if they caught the girl.
3) was mugged, and the first set of cops that showed (about 10-15 minutes) up told me that I wasn't their problem, that I was on the wrong side of the line. Called the cops from the right precinct. They showed up in about 15-20 minutes. Never mug a graphic artist - the guy got 30 years - he's probably out already.
4) had a moving truck broken into. They didn't even want to come by - they just wanted to take a report on the phone.
5) while testing a dialing script, I inadvertently had the computer dial 911. They were at my door in about 15 minutes.
It's supposed to portary them as "wrong", that's what HCI does best.
