Was your neck injured due to a crime? Maybe target this app as a public safety tool, not a vigilante crimestopper system.

Edit: A really great angle is allowing groups of people to get notified together. Works best with phone integration. At my last company I created a 9-1-1 product that does exactly that. A user could load neighbours or relatives to be alerted and listen in to their 9-1-1 calls. That way if, say, an elderly relative called 9-1-1, nearby family could perhaps intervene (for minor stuff or cases where the caller is suffering from a mental lapse) or at least know what's going on immediately.

This is also a great value add to businesses or campuses that want to know about emergencies in real time for coordinated response. Or just to know when paramedics come in the front door, who is having the incident so they can efficiently direct them.
