Hi,
I agree it would be a great program, but there are problems, you would need to fill out a ton of information so it would be effective in calling the authorities, also what would you consider an act of crime what would somebody have to do to trigger it? If its to sesitive the user may accidently trigger it and you would be reporting yourself to the authorities. I'm not trying to put you down, I really like your idea, but how would you want it to work?
And don't even start thinking about jurisdiction!!!!!
